Hardwired

Hardwired (pronounced hahrd-whyid)

(1) In electronics, built into the hardware.

(2) In mainframe computing, a terminal connected to the CPU(s) by a direct cable rather than through a switching network.

(3) In the behavioral sciences, a cluster of theories pertaining to or describing intrinsic and relatively un-modifiable patterns of behavior by both humans and animals.  Published work describes genetically determined, instinctive behavior, as opposed to learned behavior.

(4) In computer programming, a kludge temporarily or quickly to fix a problem, done historically by bypassing the operating system and directly addressing the hardware (assembly language).

(5) Casual term for anything designed to perform a specific task.

1969:  A compound word: hard + wired.  Hard was from the Middle English hard from the Old English heard, from the Proto-Germanic harduz, derived ultimately from the primitive Indo-European kort-ús from kret (strong, powerful).  Cognate with the German hart, the Swedish hård, the Ancient Greek κρατύς (kratús), the Sanskrit क्रतु (krátu) and the Avestan xratu.  Wire was from the Middle English wir & wyr from the Old English wīr (wire, metal thread, wire-ornament) from the Proto-Germanic wīraz (wire) from the primitive Indo-European wehiros (a twist, thread, cord, wire) from wehy (to turn, twist, weave, plait).  The suffix ed was used to form past tenses of (regular) verbs and in linguistics is used for the base form of any past form.  It was from the Middle English ede & eden, from the Old English ode & odon (a weak past ending) from the Proto-Germanic ōd & ōdēdun. Cognate with the Saterland Frisian ede (first person singular past indicative ending), the Swedish ade and the Icelandic aði.  The earliest known citation is from 1969 although there are suggestions the word or its variants had been used earlier, both in electronics and forms of mechanical production, the word migrating to zoology, genetics and human behavioral studies in 1971. The spellings hardwired, hard wired and hard-wired are used interchangeably and no rules or conventions of use have ever emerged.

The coming of the wireless hardware devices really pleased many women who, for whatever reason, often showed an aversion to the sight of cables, whether lying across the floor or cluttering up their desks, noting their curious way of attracting dust and, adding insult to injury, an apparently insoluble tendency to tangle.  There are though still genuine advantages to using a cabled connection and although wireless headphones have long been the preferred choice of most, there remains a niche in which the old ways still are the best.  The advantages include (1) typically superior sound quality (which obviously can be subjective but there are metrics confirming the higher fidelity), (2) no batteries required, (3) inherently lower latency (thus ideal for gaming, and audio or video editing because of the precision in synchronization, (4) simplified internal construction which should mean lower weight for equivalent dimensions mass and improved reliability and (5) close to universal compatibility with any device with headphone jack or adapter.  The drawbacks include (1) one’s physical movement can be limited by the tethering (thus not ideal for workouts), (2) cables can be prone to damage, (3) cables can be prone to snags & tangles, (4) compatibility emerging as an issue on mobile devices with an increasing number lacking headphone jacks or demanding adaptors.  Of course for some the existence of Bluetooth pairing will be a compelling reason to go wireless and it has to be admitted the modern devices are now of such quality that even lower cost units are now good enough to please even demand audiophiles.

SysCon

IBM explains by example.

In the pre-modern world of the mainframes, there might be a dozen or thousands of terminals (a monitor & keyboard) attached to a system but there was always one special terminal, SysCon (system console), hardwired to the central processor (something not wholly synonymous with the now familar CPU (central processing unit) in PCs.  Unlike other terminals which connected, sometimes over long distances, through repeaters and telephone lines, SysCon, often used by system administrators (who sometimes dubbed themselves "SysCon" the really nerdy ones not using capitals), plugged directly into the core CPU.  When Novell released Netware in 1983, they reprised SysCon as the name of the software layer which was the core administration tool.

Google ngram: The pre-twentieth century use of "hardwired" would have been unrelated to the modern senses.  Because of the way Google harvests data for their ngrams, they’re not literally a tracking of the use of a word in society but can be usefully indicative of certain trends, (although one is never quite sure which trend(s)), especially over decades.  As a record of actual aggregate use, ngrams are not wholly reliable because: (1) the sub-set of texts Google uses is slanted towards the scientific & academic and (2) the technical limitations imposed by the use of OCR (optical character recognition) when handling older texts of sometime dubious legibility (a process AI should improve).  Where numbers bounce around, this may reflect either: (1) peaks and troughs in use for some reason or (2) some quirk in the data harvested.

In recent decades, the word “hardwired” has become a popular form, used figuratively to describe traits, behaviors, or tendencies believed to be innate, automatic, or deeply ingrained, the idea being things “permanently programmed into a human or animal”, on the model of the fixed circuitry in an electronic device.  Although probably over-used and sometimes with less than admirable precision, the term has come to be well-understood as referring to things (1) biologically pre-determined (instincts, reflexes), (2) psychologically ingrained (personality traits, cognitive biases) or (3) culturally conditioned but so deeply entrenched they appear intrinsic.  Even in professions such as medicine, psychiatry & psychology, all noted for their lexicons of technical terms with meanings often (in context) understood only by those with the training, in colloquial use it has become a popular metaphor.  It seems also to be an established element in academic writing because it’s such convenient verbal shorthand to convey meaning.  In that sense, it’s an acceptable metaphor in a way the phrase “it’s in the DNA” is not because that can be literal in a way “it's hardwired” cannot because living organisms have no wires.  DNA (deoxyribonucleic acid) is the famous double helix of polymers which constitute the so-called “building blocks” of life and sometimes the expression “it’s in the DNA” simply is incorrect because what’s being discussed is not connected with the double helix and it would be better to say “it’s hardwired” because the latter is vague enough to convey the idea without be so specific as to mislead.  The best use of the metaphoric “hardwired” is probably in neuroscience because the brain’s neural circuits may directly be compared with electronic circuitry.  The difficulty with using “hardwired” in the behavioural sciences is that very vagueness: it’s not helpful in suggesting where the lines exists between what’s determined by evolution and what are an individual’s temperamental traits.  That said, it remains a useful word but, used carelessly, it can overstate biological determinism.

Horology

Horology (pronounced haw-rol-uh-jee)

(1) The science of time.

(2) The art and science of making timepieces or measuring time.

(3) In Orthodox Christianity, the office-book of the Greek Church for the canonical hours.

1852: The construct was the Ancient Greek hōro (combining form of hra (hour; part of the day; any period of time)) + -logy.  The suffix -ology was formed from -o- (as an interconsonantal vowel) +‎ -logy.  The origin in English of the -logy suffix lies with loanwords from the Ancient Greek, usually via Latin and French, where the suffix (-λογία) is an integral part of the word loaned (eg astrology from astrologia) since the sixteenth century.  French picked up -logie from the Latin -logia, from the Ancient Greek -λογία (-logía).  Within Greek, the suffix is an -ία (-ía) abstract from λόγος (lógos) (account, explanation, narrative), and that a verbal noun from λέγω (légō) (I say, speak, converse, tell a story).  In English the suffix became extraordinarily productive, used notably to form names of sciences or disciplines of study, analogous to the names traditionally borrowed from the Latin (eg astrology from astrologia; geology from geologia) and by the late eighteenth century, the practice (despite the disapproval of the pedants) extended to terms with no connection to Greek or Latin such as those building on French or German bases (eg insectology (1766) after the French insectologie; terminology (1801) after the German Terminologie).  Within a few decades of the intrusion of modern languages, combinations emerged using English terms (eg undergroundology (1820); hatology (1837)).  In this evolution, the development may be though similar to the latter-day proliferation of “-isms” (fascism; feminism etc).  Descents of the Greek hōro came into use in many languages including the Hebrew הוֹרָה (hóra), the Romanian horă and the Turkish while from the Modern Greek χορό (choró) (accusative of χορός (khorós) (dance)) came Hora, a circle dance popular in the Balkans and Israel. In Late Latin, the derived form was horologium.

Between the early sixteen and nineteenth centuries the meaning was restricted to describing clocks or their dials by at least 1820 reference books were noting “term horology is at present more particularly confined to the principles upon which the art of making clocks and watches is established”.  The earlier sense in English reflected the inheritance from the Latin horologium (instrument for telling the hour (and in Medieval Latin “a clock”), from the Ancient Greek hōrologion (instrument for telling the hour (ie the sundial; water-clock etc), from hōrologos (telling the hour).  Horological was used as early as 1590s, horologiography (the art or study of watches and timepieces) by the 1630s and the first horologists (the practitioners of horologiography) appeared to have emerged (or at least first advertised themselves) in 1795.  The noun horologe (a clock or sundial) is long obsolete.  Horology, horologiography & horologist are nouns, horological is an adjective and horologically is an adverb; the noun plural is horologists.

Greenwich Mean Time

Greenwich Mean Time (GMT) is the mean solar time at the Royal Observatory in Greenwich, London.  It’s daily reset point is now midnight but, in the past, it has been set from different times including at noon and for this reason, if GMT is of substantive importance in some historic document, it’s sometimes necessary to determine which method of calculation applied at the time.  Because of Earth's uneven angular velocity in its elliptical orbit and its axial tilt, noon (12:00:00) GMT is rarely the exact moment the Sun crosses the Greenwich meridian and reaches its highest point in the sky.  The event may occur up to 16 minutes before or after noon GMT, a discrepancy included in the calculation of time: noon GMT is thus the annual average (ie "mean") moment of this event, which accounts for the "mean" in GMT.  In the English-speaking world, GMT is often used as a synonym for Coordinated Universal Time (UTC) and while this is close enough for many practical purposes, in the narrow technical sense GMT is now a time zone rather than time’s absolute reference.  For navigation, it is considered equivalent to UT1 (the modern form of mean solar time at 0° longitude); but this meaning can differ from UTC by up to 0.9 seconds so GMT should no longer be used for purposes demanding a high degree of precision.

Shepherd Gate (slave) Clock, Royal Observatory, Greenwich.

The Shepherd gate clock is installed at the gates of the Royal Observatory in Greenwich and was the first clock ever to display GMT to the public.  It is a “slave clock”, hardwired to the Shepherd “master clock” which was first commissioned at the observatory in 1852.  One obviously unusual aspect of the gate clock is that it has 24 hours on its face rather than the typical 12, thus at 12 noon the hour hand is points straight down rather than up.  In digital timepieces are common and the user often has the choice of a 12 or 24 hour format by in analogue devices they’re historically rare although Ford Australia did include one as a novelty in the first series of its locally produced LTD & Landau (1973-1976).  The clock remained a one-off.

Between 1852-1893, the Shepherd master clock was the baseline of the UK’s system of time, its time was sent over telegraph wires to London and many other cities including some in Ireland and from 1866, the signal was also relayed to a clock in Harvard University, Cambridge, Massachusetts, along the new transatlantic submarine cable.  One of history’s most significant clocks, it originally indicated astronomical time, in which the counting of the 24 hours of each day starts at noon though this was later changed to starts at midnight.  It continues to show GMT and is never adjusted for daylight saving time.

Nipple

Nipple (pronounced nip-uhl)

(1) In anatomy, the small, conical projection near the center of the areola of each mammary gland (breast); also called mamilla, papilla or teat.  In females, the nipple contains the outlets of the milk ducts.

(2) Something resembling (often in scaled-up form) a female’s niipple, as the mouthpiece of a nursing bottle or pacifier (in some places an informal word for a pacifier).

(3) Any device resembling a nipple in shape or function.

(4) A mechanical device through which liquids or gases can be passed in a regulated manner; as grease nipple a small drilled bush, usually screwed into a bearing (or other component needing periodic replenishment of a greasing agent) through which grease is introduced.

(5) In plumbing & gas-fitting, a short piece of pipe with threads on each end, used for joining valves.

(6) Any small physical protrusion on an automotive, a machine part or any other part that fits into a groove on another part (now rare).

(7) In computer hardware, the pointing device in the centre of the keyboard of certain laptops, partially fulfilling the functionality of a mouse, trackball or track-pad (although some (usually male) users insist it is called “the clit”).

(8) In pre-modern ballistics, a perforated segment that fits into part of the breech of a muzzle-loading gun, on which the percussion cap is fixed.

(9) In the design of bicycles, an internally threaded piece which holds a bicycle spoke in place on the rim.

(10) To fit (a baby's bottle etc) with a nipple (archaic).

(11) To give one's nipple to (a baby) to allow breastfeeding (archaic).

1520–1530: From the Middle English nipple, from the earlier neble, nibble, nible & nepil (all of which may be derived from nib & neb (tip; point).  The Old English nypel (elephant’s trunk) was formed analogously as “a protuberance from one's neb”.  The late twelfth century pap & pappe (nipple of a woman's breast) was first attested in Northern and Midlands writing, probably from a Scandinavian source (there’s no record in the Old Norse but there was the dialectal Swedish pappe), from the primitive Indo-European imitative root pap- (to swell), the source also of the Latin papilla (nipple) which may have influenced the English papula (a swelling, pimple) and the Lithuanian papas (nipple).  The spellings neple, nypil, nyppell, neapel, neaple, neble and all obsolete.  Nipple is a noun & verb, nippling is a verb and nippleless & nippled are adjectives; the noun plural is nipples.

One extinct verb which, perhaps surprisingly, wasn’t revived even after it became apparent trends of use on the internet suggested it might be helpful, was expapillate (bare the breasts to the nipples), identified by the outstandingly good OnlineEtymology Dictionary as an entry in an early English "dictionary", published in eleven editions between 1623 and the 1650s.  The book was neither a prescriptive or descriptive work encompassing the whole language but was described as “An Interpreter of Hard English Words”, an approach others later took including Wilfred Funk (1883–1965) in his Word Origins and Their Romantic Stories (1950), the idea being to focus on the less known or more obscure.  The construct of expapillate was ex- + papillate.  The ex- prefix was from the Middle English, from words borrowed from the Middle French, from the Latin ex (out of, from), from the primitive Indo-European eǵ- & eǵs- (out).  It was cognate with the Ancient Greek ξ (ex) (out of, from), the Transalpine Gaulish ex- (out), the Old Irish ess- (out), the Old Church Slavonic изъ (izŭ) (out) & the Russian из (iz) (from, out of).  The “x” in “ex-“, sometimes is elided before certain constants, reduced to e- (eg ejaculate).  The Latin papillate was the vocative masculine singular of papillātus (having nipples or buds; shaped like a nipple or bud) and was used in English as a transitive verb (to cover with papillae) and intransitive verb (to take the form of a papilla, or of papillae).

In 1974, The British Medical Journal (BMJ) used the term "guitar nipple" to describe "the irritation to the breast that can occur from the pressure of the guitar against the body."  That was indicative of the trend in the English-speaking world for newly-identified (and sometimes novel) conditions to be constructed with English elements, rather than the Latin historically used.  In the same spirit, two years later a contributor to the Journal of the American Medical Association (JAMA) was more imaginative still, coining "hot pants syndrome" when documenting cases in which a burn to the skin had been induced by a patient carrying a battery-powered transistor radio in the pocket of their trousers.  There was also in 1978 the New England Journal of Medicine's (NEJM) "disco digit" which referred to "a sore or infected finger caused by too much finger snapping while dancing."    

Jaguar tool kit supplied with 1966 E-Type (XKE).  The grease gun (left) was used to force grease into various components through grease nipples.  This was a regular part of automobile maintenance until recent decades and is still a feature of the maintenance schedules of heavy vehicles and machinery.

Until the 1970s, it was common for cars to need periodic “greasing” of certain components, a process which involved attaching a “grease gun” to a “grease nipple” which was permanently mounted to the relevant part and manually, the gun (usually a type of plunger) was used to force grease through the nipple.  This was undertaken either by owners, chauffeurs or mechanics at service stations who routinely would perform an “oil and grease” (changing the engine (and sometimes the gearbox and differential) oil, replacing the filter(s) and greasing all required grease points.  On more expensive vehicles, “one-shot lubrication” systems (known also as centralized lubrication systems (CLS) or automated lubrication systems (ALS) were introduced during the 1920s, the technology adapted from those used in aviation.  Although some attempts were made to create wholly automated systems, the most widely used were those which incorporated a foot pump for the driver to press at specified intervals; this action forced grease from a central reservoir to the required points.  Being a sealed system, this meant that nowhere in the system were grease nipples required (although some may still have been fitted to parts which required less frequent attention.  ALS systems remain common in many places including heavy machinery, ships and the industrial plant used in factories, power plants etc.

The standard grease nipple used on the Jaguar E-Type (XKE) (left) and a diagram with a legend listing the E-Type's oil, brake fluid, transmission fluid and grease nipple locations.  The grease nipples are indicated by the obelus ().  In automobiles, by the 1970s the need for multiple grease points or one-shot lubrication had begun to be eliminated (although some older designs maintained the legacy for decades) as advances in metallurgy and lubrication technology permitted the development of sealed, maintenance-free components which are “packed with grease" and thus “lubricated for life”.  However, for heavy-duty machines such as trucks and earth-moving equipment operating in adverse conditions, there are often still components demanding regular greasing and thus grease nipples are still a thing.

Also a thing is the “nipple orgasm”, at least for those for whom a nipple is a “hardwired erogenous zone” responsive to stimulation.  Although in humans orgasms are typically thought of as a ejaculative, vaginal or clitoral phenomenon, sexologists list more than a dozen types, varying in instance or intensity based on the individual, the circumstances and sensitivity to stimulation.  When warming to the topic, these specialists will also discuss the details of “energetic orgasms” (which can, without physical touch, be triggered by meditation or fantasy) and “sleep orgasms”, said to have been experienced by an “estimated” 37% of women and 83% of men.  Quite how those numbers were obtained isn’t clear but helpfully, in 2011, New Jersey-based neuroscientist, psychotherapist & sex therapist Dr Nan Wise (b 1967) undertook a study to reveal how nipple stimulation affects the brain.  What Dr Wise wanted to build on was the existing understanding “…the clitoris, vagina and cervix are mapped on the genital sensory cortex”, something which sits between the brain’s two hemispheres and which she labels “hedonistic pleasure zone” or, more illustratively “the crotch of the brain”.

What Dr Wise did was have the study’s subjects stimulated with various mental fantasies while in an MRI (magnetic resonance imaging) machine, allowing her team to observe how distinct parts of the brain responded to various experiences.  The results were generally in line with expectations except that nipple stimulation proved an outlier.  While her hypothesis had been there would have been activity in the brain region associated with chest sensation (the theory being nipple orgasms might occur because stimulation of the organ releases oxytocin, a hormone that can cause uterine contractions, potentially leading to vaginal orgasm), instead it was found nipple stimulation activated the genital sensory cortex itself, leading Dr Wise to conclude: “The nipples are a hardwired erogenous zone, like the genitals, when nipples are stimulated, the brain gets activated, and regions processing the sensation communicate with those responsible for pleasure.”  This tied in with one of the accepted dictums in neuroscience: “neurons that fire together wire together” and the study’s findings do seem to suggest it is plausible there exists a neural pathway between the nipples and the genitals.  Sexologists however caution individual responses will vary and techniques which produce pleasing results for one will induce no response in others.  So, YMMV (your mileage many vary) and the sexologists recommend experimentation.

The SKIMS Nipple Bra

Wearing it well: Kim Kardashian in SKIMS "nipple bra"

The admirable (and much admired) Kim Kardashian (b 1980) in October 2023 announced the latest addition to her SKIMS product line: a bra with “built in” nipples, designed to be prominent enough obviously to protrude through clothing.  Said to offer the “ultimate shock factor” (although after the shocks of the last decade-odd, some of which members of the Kardashian clan have instigated, that may be hyperbolic) the viewer response suggested many weren’t certain whether product was real or a gimmick designed to attract publicity.  It certainly attracted publicity but turned out to be a real with a SKIMS' part number.  Even if the concept wasn't as “innovative” as claimed, the promotional approach in the video certainly was, the spin being that if women can don a bra to emulate one of the better known consequences of cold weather, the psychological effect might be such that they’ll be less inclined to turn on (or up) the air-conditioner, thus reducing energy use, thereby lowering carbon emissions, meaning a lesser contribution to the concentration of atmospheric CO2 (and other greenhouse gasses) which causes accelerated climate change including higher temperatures.  That seems to be drawing a long bow but doubtlessly somewhere there will be published research which can be spun to support (or at least not disprove) each of the steps in the Kardashian logic.

As Ms Kardashian put it: “The earth’s temperature is getting hotter and hotter. Sea levels are rising. The ice sheets are shrinking. I’m no scientist, but I believe everyone can do their skillset to do their part.  That’s why I’m introducing a brand-new bra with a built-in nipple so matter how hot it is, you’ll always look cold.  Some days are hard but these nipples are harder. And unlike the icebergs, these aren’t going anywhere.  The bra will be available in six colors and a stated “10% of sales” (the exact math of that calculation not disclosed) will be given in a “one off donation” to 1% for the Planet (a multi-national collective of businesses pledged to gifting at least 1% of the annual revenue to “environmental causes”).  So it sounds like a real product with a real part-number (not yet listed) but there were those who thought the release date being Halloween (October 31) suggested it might not be wholly serious.  Even if not, it was a good promotional video, the only opportunity missed being Ms Kardashian should first have appeared in a scientist's white lab coat, peeling it off as she spoke the words "I'm no scientist".

The 1970s: Rudi's sheer bra (left & right) and the original Nipple Bra.

It’s actually not a new idea.  In the early 1970s, several manufacturers advertised a line of bras with cups in a sheer fabric which offered coverage and support (within a small size spectrum) but clung to the nipples' definition, the most celebrated being those of Austrian-born Rudolf "Rudi" Gernreich (1922–1985), remembered as the "designer" of the "monokini" (ie a bikini supplied without the top part).  This approach was for those who wanted to display the profile of their own nipples.  The "Nipple Bra" offered enhanced engineering was athe ancestor of the SKIMS bra in that rather than using, as Herr Gernreich did, the human body's "built-in" nipples, it provided some.  The pitch all those decades ago was aimed at those who wanted to look “provocative” and in 1975 to achieve that the “Nipple Bra” cost US$20 (US$114.42 adjusted for 2023) so Ms Kardashian setting her price at US$120.00 seems not unreasonable.  The somewhat obtuse contribution to averting climate change aside, reaction to the product included the observation the bra will provide permanently “perfectly aligned nipples”, something not always achieved by the real things because, like most body parts, between left and right, there’s often some variation in size, shape, direction or distance from the ground.  Like many aspects of structural engineering, “perfect alignment” is achieved often with slight adjustments to variables like strap length.

In the United States, patent law exists to protect inventions, processes, and methods rather than abstract ideas and the general criteria (interpreted with some latitude) for eligibility is that an invention should be novel, non-obvious, and useful.  What does qualify is the implementation or embodiment of an idea in a tangible form so while a mere thought or concept can't be patented, a specific application or embodiment of that idea can be and this includes a new product, process, machine, or composition of matter.  Within all that, patents can be granted to cover improvements made to existing inventions.  Whether SKIMS have applied for or been granted a patent isn't clear but several for products in this vein have been granted over the last 50-odd years.  On 24 August 1976 Mr Jakob E. Schmidt of Charlestown, Indiana was granted U.S. patent #3976083 (Brassiere Having Simulated Nipples) as well as #4241737 & #4127128 covering “Brassiere Having Simulated Nipples and Attachable-Detachable Nipple Simulators”.

Conceptual drawing supplied with application for patent #3976083 (Brassiere Having Simulated Nipples), granted 24 August 1976.  The patent expired 24 August 1993.

The abstract filed with the application for #3976083 included: A brassiere is disclosed having cups which are provided with a nipple-like protuberance simulating the bulge of a natural nipple. The nipple-like bulge or protuberance may be a built-in component of the brassiere, usually situated under the fabric of the cup; a component which is permanently attached to the external surface of the brassiere cop; or an individual structure which may be attached to or detached from the brassiere cup as will, by means of several linkage and attachment mechanisms.  Simulated nipples for a brassiere would offer an acceptable compromise for ladies who do not wish to go without a brassiere and a welcome release from the subconscious effects of the suppression brought on by wearing brassieres of the types variously available, which obliterate the nipple.  That’s informative but Ms Kardashian might have phrased things a little differently. 

A nipple patch (left), the nipple patch writ large to function as a special-purpose bra (centre) and the advertising concept (right) which could be used by the manufacturers of either the "nipple bra" or the "nipple patch".  All that would be required is transposing the photographs, depending on whether the object was to display or conceal.

However, while one niche market will like the idea of being “so provocative”, there are others who find the sight of their own nipples “too provocative” and for this niche, there are ranges of products which offer coverage and concealment, smoothing away any suggestion of a nipple with patches which can be worn under bras with cups of even the most sheer fabric.  Self-adhesive (using a skin-friendly temporary glue), they can also be used without a bra and the same technology has been adapted to larger-scale units which actually function as a bra.  Marketed as being ideal to be used when wearing “backless” dresses or tops, they’re also said to be easier to use than the “fashion tape” (better known in the industry as “booby tape” or “tit tape”), especially if being self-applied.  Helpfully, if one changes one’s mind after having smoothed away the nipples, stick-on nipples are available in a range of styles and colors.
