"Bras Make Breasts Sag, Study Suggests"

"Since 1997, he has been studying the breasts of 330 volunteers ages 18 to 35 using a slide ruler and a caliper to record the changes in breast position as the women aged, CBSNews.comreports.

His meticulous research revealed that women could experience about a 1/4-inch (7-millimeter) lift in the nipples each year they didn't wear a bra, news site Counsel & Heal reports.

The researchers involved in the study suggested that bras — which Rouillon now calls "a false necessity"— discourage the growth of supporting breast tissue, leaving the breasts to sag more quickly."
