There is a direct correlation between income and intelligence. There is an inverse correlation between income and cardiovascular risk.
I'm taking bets that intelligence influences cardiovascular risk. Like maybe, smart people understand health risks and act to avoid those risks... Being dumb is a harsh burden in life.
Lol, and how many times have I been asked: if you are so smart, how come you are not rich?
Intelligent people are more motivated for good health, usually. For me life is good, I have not peaked mentally; in my opinion :)
There is a continuous flow new adventures, relationships, challenges and opportunities. There must be a minimum income level to persue it all, but you don't have to be wealthy.
