Bras Make Breasts Sag, 15-Year Study Concludes.

You may wonder,how is it possible but the truth is that,using bra makes your breast to sag, Jean-Denis Rouillon, a sports science expert from the University of Besançon, France, reported after a 15-year study.
Rouillon says that the main conclusion from the preliminary results of his "marathon experiment" is that the bra is a false necessity.
In an interview with France Info (radio), Professor Rouillon said:
"Medically, physiologically, anatomically - breasts gain no benefit from being denied gravity. On the contrary, they get saggier with a bra."
In his studies Rouillon found that women who never wore bras had nipples on average seven millimeters higher in relation to their shoulders each year than regular bra users.
The reason behind this is that,not wearing a bra causes a pull on the breast due to gravity,which encourages the production of elastin and other proteins that makes the breast elastic and firm.
The study was conducted on hundreds of women from different age groups.Although study many not be the true representative of the globle population,yet it gives a window for further study.
According to Rouillon a much extencive study is needed to prove or disprove the results of the study which he conducted.
