Excessive brain activity linked to a shorter life
Greenwich Time ^ | 17 Oct 2019 | Carolyn Y. Johnson

Posted on 10/17/2019 8:25:57 AM PDT by DUMBGRUNT

"The completely shocking and puzzling thing about this new paper is . . . [brain activity] is what you think of as keeping you cognitively normal. There's the idea that you want to keep your brain active in later life," said Michael McConnell, a neuroscientist at the Lieber Institute for Brain Development, who was not involved in the study. "The thing that is super unexpected is . . . limiting neural activity is a good thing in healthy aging. It's very counterintuitive."

One model, called "CRUNCH," tries to explain changes in patterns of brain activation with age. It says that when people attempt harder and harder tasks, more regions of their brain are activated, until they reach a crunch point where they run out of mental resources. Older people have an earlier crunch point and can't activate as many regions. Another, called "STAC," says older adults have natural variation in their basic scaffolding of natural cognitive resources, and those variations influence how and whether people can engage more neural regions when faced with difficult tasks.

Another useless “study”. For years we’ve been told just the opposite, in study after study. So, yawn...

Sounds good to me. The only reading I do is FR and Facebook. My brain must be pretty good. Laziness has turned into a positive!

Protect them from death? Lol. Now that is funny while they take brain samples from the corpse.

So how is it that women usually live longer than men when they can’t shut their brains and mouths off all day?-)

I do too. If anything, staying very active mentally and intellectually seems to prolong life. Here’s a list of scientists and mathematicians who lived to be over 100:

I also always think of Jacques Barzun, who lived to be 105 and absolutely sharp to the end.

Octavia 92 has full Alzheimer’s oppositional defiance, she is shortening the life of her relative by marriage who swore to care for her.

She says the other night, about an ADHD boy who uses too much soap, “put it in little bottles”.

She says about a woman’s troubled marriage, “she’ll lose her husband”.

She says about a negligent mother, “sounds like she’s getting ready to abandon the kids”.

Doing X is good for you.
No, doing X is bad for you.

Oh, wait. A new study shows that doing X is good after all.
This just in. More research shows that doing X is harmful.

On and on it goes...

So, are the Harvard researchers saying that lots of REST is a good thing?

Yeah, but... if we stop thinking, does it necessarily mean we have to become demoRATS? ‘Cause demoRATS are so stupid that they’re incapable of even the simplest thoughts! They’ll practically live forever if using your brain means a shorter lifespan!
