Cartilage is really the final frontier of health. If it wasn’t for joints going bad, people could stay very active and fit pretty much all their life, with consistent exercise and healthy weight.


I'd say spinal and optic nerve regeneration is more "final" than cartilage.


Well yea but not in terms of the amount of lives that will be improved.


Alzheimer's and similar, matter a lot too. Brain controls body.
