Note that life insurance isn't going to be a good model--there are two selection biases at work here. 1) Those in ill health likely can't afford life insurance. 2) Life insurance is mostly to provide for dependents--which means people in good enough shape to have dependents and people are young enough to still have dependents. (Once the kids are grown there's much less reason for term life insurance.)
