A forthcoming article in the
British Medical Journal provides evidence that IQ affects long-term health prospects, even after controlling for socio-economic factors, though these also have some independent effect. An abstract of the article is
here. I think this research may already have been mentioned somewhere (I noticed it in today's London
Times, but it seemed vaguely familiar), but it can do no harm to mention it again.
Added: I didn't mean to imply that this was the first research to show a link between IQ and health. As several people have pointed out, there are previous studies. But this one may be unusual in covering people fairly late in life (up to age about 70).
