The odds are in my favour I guess, my average is like 87-93 years... that's a lot of years left.
My only weakness is I put 0 for any physical activity, but then they tell me it would only add 1-2 years. That really doesn't seem like it's worth it, now I don't want to exercise ever again.
I got both diabetes and heart diseases running in my family and I'm doing my best to avoid these, but who knows... One can only try to minimize the risk, eh.
