A new study out of France that followed women for 15 years has determined that bras are bad, m'kay? "Medically, physiologically, anatomically, breasts gain no benefit from being denied gravity. On the contrary, they get saggier with a bra."
The researcher, one Jean-Denis Rouillon at the University of Besancon in France, said that women who don't wear bras tend to be perkier, have less back pain, and have better posture.
Okay, I'm sure this guy thought he covered all the bases, but if you think about it...bras came about because of the need for support. Sure, it'd be nice if bras actually defied the effects of gravity, but if you're well endowed, gravity is going to take its toll regardless of whether or not you've worn a bra. That's especially true if you've had kids, since you have to factor in sagginess due to the skin being stretched when you go up in cup size while you're pregnant and nursing.
Now think about the women who are more likely to go bra-less. They're probably not the women who are super well-endowed: you don't need as much support if you're smaller. If you're smaller, then you're more likely to be...you guessed it - perkier! Smaller means less to no back pain, and if you're not so well endowed, you might be more likely to have better posture since you're not fighting an internal tug of war between your back and your chest.
I don't know about you, but it kind of sounds to me like this guy wasted 15 years. Either that, or it was a really good excuse to "examine" women without getting in trouble with his wife.
