I believe if we age and continue flying it will kill us much sooner than that. This is highly controversial topic.. I imagine some irate responses here... FAA retirement age used to 60 and now relaxed to 65. Rought rule of thumb? I don't know what the right age is but it is probably different for each person. Question is, will each person know when it is time.
