Boob to Belly 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.

Yes, urbandictionary is the most legit, premier source for definitions. Is B to B a downgrading term to 'objectify' people? Perhaps. This is however one of the most important factors in your life. Yeah, one can argue looking good or 'hot' is something our society created to glorify a certain lifestyle etc, but in the end, there's a reason why society glorifies the good B to B ratio.
It's healthy.
A study published in The New England Journal of Medicine that looked at more than 350,000 people found that a large waist can nearly double your risk of dying prematurely -- even if your weight is "normal" (according to your body mass index, a measure of body fat based on height and weight).* Some people who don’t exercise but generally keep their overall body weight under control, for example, may have dangerous fat deposits around the abdomen.
An increasing body of evidence is now linking belly fat to other serious health risks, such as...
Cancer. Both men and women with higher percentages of belly fat are more likely to develop a variety of cancers, including malignancies of the colon, kidney and breast.
Dementia. In a study of 6,583 adults, the bigger the belly, the greater the risk for dementia.
Surprising finding: Among those of normal weight who had excess belly fat, dementia risk was 1.89 times higher than for those of normal weight who did not have excess belly fat.Lung problems. Lung function is reduced in patients with higher stores of belly fat, possibly because of the higher secretion of lung-damaging inflammatory chemicals.
Diabetes. An apple-shaped fat distribution greatly increases the risk for insulin resistance (a condition in which the body’s cells don’t use insulin properly) and diabetes.
The risks are even higher in those who are sedentary. People who have lost muscle mass, as a result, take in less blood sugar (glucose), which is used as fuel -- further increasing diabetes risk.Migraines. Researchers at Drexel University College of Medicine found that women with large amounts of belly fat were up to 30% more likely than lean women to suffer from migraine headaches.
So why not look good and not die in a hospital bed crying in pain at the same time? The thing that pisses me of the most is that people who comes up with excuses to not be healthy. Not because I care about your health, but if you get sick, you're just draining from society.
