I'm a vitamin junkie (Don't pick on me, it's my FSM), so I've been taking low-dose aspirin for over a decade now. If I remember my health-nut mythology correctly, the theory is that inflammation (and especially inflammation related to blood sugar spikes) is believe to be a contributing factor to a lot of bad stuff: diabetes, cancer, aging, and so on.
Interesting to see aspirin continuing to make the news. Amazing drug.
