When I integrate the curve in the post from 25 to 300, I get 52.34. (When you integrate a cdf, you get an expected value- that’s how many years I have left, on average.)
Please correct me if I’m wrong, but it appears that the curve in question cannot be a cdf because it is clearly not nondecreasing.
