As much as I tried to estimate a death probability by using publicly available data (77M, weight ~230lb, medicated cholesterol, non-smoker, likely average drinker, normal blood pressure), the best I could do was to use the raw actuarial table estimate, which puts him at ~5% annually. Given regular checkups and medical attention, I'm guessing it could even be half that, ~2.5%.

If someone can run the full estimate with the risk factors, I would be curious about the result!
