I am not understanding you thought process here. By buying that term he ensured that he had coverage for that long whereas had he taken a shorter term and cv became uninsurable then he would be left without coverage at the end of the term even though it was even more needed then.
Case in point: an existing client who bought from me two term policies almost 10 years ago, one being a 30-year term, and the other a yearly renewable term, decided he needs more insurance now, and split his additional coverage between new 30-year and new 15-year term policies, and considering conversion of the yearly renewable term to permanent insurance. The old 30 year policy is being kept for the 20 years it still has.
Also paying annually rather than monthly automatic payments can serve as a reminder to review (but could run the risk of a missed bill/payment).
