Good point. To clarify, many people buy Term Life when they are healthy. You lock in long-term savings for 5, 10, or 20yrs. Renewing term life 10yrs or 15yrs in is hard -- you now have high cholesterol, diabetes, risk, etc., so your premiums go up massively. It defeats the point of term life.
Is that practically feasible though, there’s a great cost favorability loss in reinsuring in a new policy years / decades after initiating a policy
