There's an interesting comment in the tweets that links to an article claiming high levels of uric acid in the blood of high achievers. The article is about the consequent prevalence of gout in that demographic.
Less well known is uric acid's effect on hypertension -- which would also perhaps (anecdotally) explain likely elevated levels of heart attack and stroke in that same demographic.
All terribly confounded, though. Hard to unravel chickens from eggs, lifestyle factors etc.
