Turns out, hippie chicks were on to something when they let their breasts hang free. According to sports scientist and professor Jean-Denis Rouillon of the Centre Hospitalier Universitaire in France, bras are bullshit; free boobing is the way to go. Roullion painstakingly took on the treacherous task of spending 15 years measuring changes in women’s breasts using a ruler and calipers. Following his observation of 130 women, Rouillon concluded that bras are a detriment to the female anatomy and "a false necessity." He explains that medically, physiologically, and anatomically – breasts gain no benefit from being denied gravity. On the contrary, they get saggier with a bra. Furthermore, they don't assist in helping with back pain and going bra-less can even help with breathing.
We aren't scientists and something tells us neither is Jean-Denis Rouillon, but we give credit to the Frenchman for doing this in the name of science. And for that we say thank you.
