Not everyone who has a stroke is down to an unhealthy lifestyle. I had one and I wasn't unhealthy or overweight . For me, it was probably genetic as both my grandmother & great-grandmother died from strokes when they were relatively young and all my uncles have had heart issues.
I've become a (mostly) vegan* and it being low fat to boot. I recently got my annual check up and the nurse told me that my bad cholesterol was the lowest she had ever seen.
Anyway, here's hoping Peter makes a full recovery and starts looking after himself and just doesn't rely on pills to help himself. I liked his Hulk up until Todd McFarlane left. Good stuff.
* My theory is that humans for most of human history had a vegetarian diet but had the odd fatted calf from time to time.
