AsapSCIENCE just released a new video, "The Science of Boobs," which delves into everything mammary because, well, breasts are pretty amazing.

The video delves into a huge number of topics, including the fact that those little dots we have on our areolas are called Montgomery's glands and are designed to keep our nipples lubricated while breastfeeding, while also making breast milk taste "yummy" for babies.

Interesting, right? But the brains at AsapSCIENCE didn't just delve into the biology. The video also reveals that while large breasts attract more attention — and are part of the reason for 300,000 breast augmentation surgeries in 2014 — it's actually medium-sized boobs that are the most universally liked. They're also a great source of sexual release, as 82 percent of women and 52 percent of men experience arousal from self-stimulation of nipples.

And then there's the scary part: Breasts are the most vulnerable to cancer, as breast cells divide at a higher rate than other parts of our bodies because of hormones (like estrogen) and growth as we age.

Whether you know all of this — or none of it — this video is a good, quick refresher on all things boobs.
