A new treatment that blocks an aging-related protein restored lost cartilage in old mice and helped prevent arthritis after knee injuries. Human cartilage samples showed similar signs of regeneration, raising hopes for a future drug that could repair joints instead of replacing them.
it’s always seemed weird to me that aging takes 20 years in dogs but 80 years in humans. i mean, if it’s a physical hardware failure, then you would expect it to be independent of age and only dependent on past physical load.
