There's good evidence that if people are disempowered, if they have little control over their lives, if they're socially isolated or unable to participate fully in society, then there are biological effects.

I don't blame people for smoking when I see a social gradient in smoking. I say we need to understand why is it the lower you are in the hierarchy the more likely you are to smoke. So we need to address the causes of the causes.

In Sweden for example people with PhDs have lower mortality than those with a masters degree. And people with a masters degree or a professional degree are not poor.

It's highly likely that what you're doing is indeed influenced by your Jewish background.

The lower you are in the hierarchy the worse your health, the higher you are, the better your health.

For every dollar spent on early child development you save $7 over the life course because children with better early child development are less likely to end up delinquent, involved in crime, unemployed and so on.

Our elected politicians do what they judge is the right thing to do. And if we disagree then I'll show them the evidence of why I disagree.
