Thanks to David Wynnt for sending this one on ( @wyadvd on twitter ). Very good discussion, and I loved his one key test for longevity that anyone can get. Yes, it's the old Post-Glucose Insulin - which he says should be below 30uIU/ml. Exactly as Kraft discovered many decades ago. It's not just cardiovascular disease guys - it's cancer too. And diabetes of course. And neurological degeneration. And...well you get the point. it's healthy longevity !!
