Poverty = poor health decisions.
I've written about this previously - but here is another speaker. A drop of 14 IQ points when you enter poverty. Or, to look at it another way:
Let's pull people out of poverty, that will result in a 14 point raise in IQ, & then people will have the means to make better health decisions. That will help reduce the health crisis we're facing, reduce healthcare cost, improve work efficiency & drive technology.
