My grandmother just celebrated her 100th birthday. She still lives on her own, drives, does her own cooking, walks unassisted, etc. When I mentioned I was going out of town for her 100th birthday party, people kept saying she must have good genes. Maybe so. Maybe she has some sort of really good RNA repair mechanism.
- ggm 3y agoIf she has a good RNA repair mechanism isn't it heritable or do you posit she bought it or made it from wool and toothpicks?
- irrational 3y agoMaybe inherited, maybe a mutation unique to herself.
- svnt 3y agoYour response seems to miss the difference between the terms inherited and heritable (because it could be heritable without being inherited), but your point is valid: whatever she has may be cognitive, biological, or otherwise, and may or may not have heritable aspects.
- ggm 3y agoA cognitive repair mechanism for RNA. That's novel. Intracellular functions are defined by gene expression, I don't think meditation or yoga is going to do it although I suppose suppression of stress hormones might influence cell function. Put it this way: it's more likely cognitive than knitting and toothpicks.

- ggm 3y agoProclivity to mutation is .. sometimes heritable. That's the BRCA gene, no? In the case of RNA repair, If it's not 50/50, there'd be an advantage in repairable RNA.
