> [0] The 90+ study: https://mind.uci.edu/research-studies/90plus-study/ https://mind.uci.edu/research-studies/90plus-study/ This plasticity idea is really neat. Anecdotal and I don’t know the correlation holds up, but my one grandmother was very set in her habits and particularly mindset and died early of Alzheimer’s and Parkinson’s. My other grandmother is flexible of mind and is still kicking it at 90+. I’m wondering which way the causality goes. Whether there is something physical which makes people more open minded and wandering whereas others are more closed which eventually leads to more brain diseases. So in the end the open mindedness / flexibility is just another indirect indicator.
