The results of a mammoth 15-year study led by professor Jean-Denis Rouillon, from the University of Besançon in eastern France, are finally in and it looks like conventional wisdom about bras and back pain has been way off the mark.
According to Rouillon, a sports science expert, the lesson to be learned from the preliminary results of his marathon experiment is that "bras are a false necessity".
"Medically, physiologically, anatomically - breasts gain no benefit from being denied gravity. On the contrary, they get saggier with a bra," Professor Rouillon said.
Using a slide rule and caliper, Rouillon spent years carefully measuring changes in the orientation of breasts belonging to hundreds of women, at the University Hospital in Besançon.
All the women involved in the study were aged between 18 and 35, although the professor was keen to stress that the group were not a representative of the global population of females.
