I should probably explain what I mean by "Fragility Barrier".
If one's adult physiological peak is in one's twenties, you will have aged half a century past your physiological peak by the time you reach your 80th birthday. Even if you retain your mental acuity into old age, by your 80th birthday your body will be quite fragile...and its decline is likely to leave your body with little capacity for work.
After that, a particular cohort will experience a sharply accelerating death rate, with only a small percentage seeing their hundredth birthdate.
