Whether they're big, small, or somewhere in between, there's more to boobs than first meets the eye.
Did you know that drinking coffee can make a woman's breasts feel more sensitive? Or that sleeping face down for a long period of time may eventually change the shape of your boobs?
The above video from Statosphere is packed full of more boobie facts like these, including how many bras are produced each year worldwide and how big the world's largest boobs are.
Spoiler alert: both answers are pretty mind-blowing.
13 Major Milestones In Boobs
3000 BC: The First Description Of Breast Cancer(01 of13)
According to the American Cancer Society, the oldest surviving description of cancer comes from roughly 3000 BC, and appears in an ancient Egyptian textbook on surgery known as the "Edwin Smith Papyrus." It includes descriptions of eight cases of breast tumors or ulcers that were treated, rather horrifyingly, via cauterization with a tool known as the "fire drill." However, the textbook also explains that there was no available treatment at the time. (credit:Getty)
1880s: First Bare Breasts On Film(02 of13)
According to Gawker, the female and male ever shown on film -- nude -- appeared between 1884 and 1887, as part of film-pioneer Eadweard Muybridge's series of men and women walking up and downstairs. It wasn't until 1915, however, that a leading actress was shown, nude, in a mainstream film (Audrey Munson, in the no-longer-available "The Perfect Model, Gawker reports). But as AMC Filmsite reports, it's Jayne Mansfield who is perhaps thought of as most as being the true "pioneer" in going topless on film: In 1963's "Promises! Promises!" she was the first woman in American feature sound film to bare her breasts and bum. (credit:Getty)
1914: The Invention Of The First 'Modern' Bra (03 of13)
The first person to patent a brassiere was a woman named Marie Tucek, who created a device with separate "pockets" for the breasts, according to an article on the MIT School of Engineering's website. It also had straps for the shoulders and a hook-and-eye closure, but the design failed to catch on. So people credit the creation of the first "modern" bra to Mary Phelps Jacob, who took two silk handkerchiefs and some ribbon and made her own. She patented the "Backless Brassiere" in 1914, before selling the patent to the Warner Brothers Corset company. (credit:Getty)
1934: 'Boobs' Enters The Lexicon(04 of13)
According to Grammarphobia, the first recorded use of the word "boob" to refer to a woman's breasts (well, "boobies," to be exact) appeared in Henry Miller's 1934 banned-tome-turned-classic, "Tropic of Cancer" -- "She was lying on the ground with her boobies in her hands," it reads. Indeed, The Random House dictionary says the word "booby" (in its use as slang for breast, not referring to the seabird or to a dunce) had its origins in the 1930s, while "boob" originated in 1945-50.

1948: The First Push-Up Bra(05 of13)
Frederick Mellinger, the man behind the eponymous lingerie company Frederick's of Hollywood, is credited with inventing the push-up bra in 1948. (He also invented the first padded bra one year earlier, Fortune Small Business reports.) According to LiveScience, the first-ever push-up came with its own rather special (and apt) name: Mellinger dubbed it "the rising star." (credit:Getty)
1956: First La Leche League Meeting(06 of13)
In 1956, at a time when breastfeeding rates in the U.S. had dipped to roughly 20 percent, the first-ever meeting of La Leche League was held at the home of Mary White, a mother of six who was pregnant with her seventh child, according to the organization's website. Seven women founded the now international organization, which supports women's breastfeeding efforts with the understanding that it has benefits for both mother and baby. (credit:Getty)
1962: The First Silicone Implants(07 of13)
The first silicone breast implants were invented by two plastic surgeons from Texas and in 1962, then 29-year-old Timmie Jean Lindsey, became the first person to receive them. She'd gone in to have tattoos removed from her breasts, and was told she'd be a perfect candidate for the procedure, the Daily News reports. According to the American Society for Aesthetic Plastic Surgery, in 2012 there were more than 1.7 million cosmetic procedures performed in the U.S. and breast augmentation (any procedure to change the size or shape of breasts) was at the top of the list.

1968: The 'Bra Burners' Myth Is Born(08 of13)
In 1968, a small crowd of women gathered to protest the Miss America pageant. They may have intended to burn their bras, but did not do so because of concerns over fire safety (the protest took place on the wood boardwalk in Atlantic City), NPR reports. The women threw bras, girdle, mops and copies of Playboy magazine into trash cans, but a New York Post article mentioned bra burning, and thus an enduring symbol of "angry" feminism was born.

1969: The First Modern Mammogram(09 of13)
Health care providers have been performing breast X-rays for decades, the American Cancer Society explains, but modern film mammography has only existed since 1969 -- the first year that X-ray units designed to be used specifically for breast imaging were invented. The machines use low levels of radiation and help improve imaging by flattening the breast tissue on an X-ray plate. Digital mammography, which still uses X-rays, but allows doctors to see (and store) an image right away and can be manipulated to help pick up subtle differences, is increasingly available (although debate over when women should begin getting regular screening mammograms rages on).

1977: Victoria's Secret Opened(10 of13)
The first Victoria's Secret was opened in 1977 by Roy Ramond in the Stanford Shopping Center in California, with a $40,000 bank loan and $40,000 he borrowed from relatives, according to a New York Times obituary for Raymond, who committed suicide in 1993. Today, Victoria's Secret (which is owned by LImited Brands) has more than 1,000 stores across the U.S. (credit:Getty)
1990: Madonna's Cone Bra(11 of13)
When the music legend went on tour for her Blonde Ambition tour, she brought with her a garment that will go down in pop-culture history: The Jean-Paul-Gaultier-designed cone bra and corset. The pink silk costume (she's since worn newer iterations) sold in a Christie's auction for $52,000, Billboard reports. (credit:AP)
1994-5: BRCA Genes Discovered(12 of13)
In 1994, geneticist Mary-Claire King discovered the BRCA1 gene. Harmful mutations to that gene can increase a woman's risk of developing breast and ovarian cancer, although as King reminded Slate -- "most cancer isn't inherited." The second so-called breast cancer gene -- BRCA2 -- was discovered by scientists in England one year later. (credit:Getty)
2004: The Biggest. Nipple Slip. Ever.(13 of13)
For anyone just crawling out from under a rock for the first time since 2004, in February of that year Justin Timberlake exposed Janet Jackson's nipple during a Superbowl halftime performance. The singers maintain it was an accident -- a wardrobe malfunction for the ages -- one that resulted in CBS (which aired the Superbowl) being fined $550,000 by the Federal Communications Commission after Jackson's breast appeared onscreen for nine-sixteenths-of-a-second, The Atlantic reports.
