The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.
the the thing is that most individuals in modern society don't do that right we do the same thing every day our work isn't cognitively challenging it's repetitive yes it's stressful yes but those are not the same thing um and so you know we're not developing new skills we're not asking our brain to do new things
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
the easiest way to see it is that when we retire multiple like now there are multiple population studies that show that the earlier you retire the earlier you experience cognitive decline or dementia
when you think broadly about how cognitive function declines with age it seems to mirror very closely the amount of demand that we put on our brains
those who retire earlier seem to experience cognitive decline sooner and that's probably because the the cognitive demand that we do get in our daily lives the majority of that comes comes from work
if you retire and in its place add nothing cognitively um you know you could expect to see a decline
sort of what I think is driving a lot of this is the amount that we actually you know ask those regions of the brain to do which does decline naturally over time um based on how we currently structure our our lifespan
you know Sally was just sharp as attack and then she retired and all of a sudden it all went to hell in a handbasket but you know you hear this so many times that you realize there must be something to this
we can see that in in various different types of data sets where those who retire earlier seem to experience cognitive decline sooner and that's probably because the the cognitive demand that we do get in our daily lives the majority of that comes comes from work
when you think broadly about how cognitive function declines with age it seems to mirror very closely the amount of demand that we put on our brains
I think some of that natural decline with aging is a function of how we use our brains in general in society and then there's a a drop off when we retire
