There isn't one.
I used to be associated with an organization for people with fairly high IQs. You would think that if behavior was driven by intelligence, that this organization would be full of successful, wealthy, healthy, socially talented, attractive people. It wasn't then and I'm sure it still isn't.
There were quite a few obese people in the group, plenty of unemployed and underemployed, tons (literally) of social outcasts. Many were relationship-challenged. Some hadn't familiarized themselves with hygiene. Some had alcohol and drug addictions.
Then there were those who were delightful and charming people who fit in fine and even excelled at their jobs.
But overall, there seemed to be plenty of overweight people with IQs in the top two percent. How could they not know how to lose weight? Or that being fat is bad for your health and for your love life?
Stupid smart people. I hope they catch on soon!
