Boob/Age, or Boob over Age.
A ratio I made up -- it's a girls boob size divided by her age.
Optimally, when diviede, the ratio should equal about 2.5. Thi is based on 35/14 (35b on a 14 year old).
Wow, she has a 2.5 b/a. Nice ratio.

Applies to both women and men. Scientists however have not come up with an optimal numerical number for such ratio, but are working with mice.
