Hibernation confirmed to slow aging

[BrianA]

"A new study shows that aging slows to a crawl when yellow-bellied marmots hibernate. These large ground squirrels are able to virtually halt the aging process during the seven to eight months they spend hibernating in their underground burrows, the researchers report.

...

All of these hibernation-related conditions -- diminished food consumption, low body temperature and reduced metabolism -- are known to counter the aging process and promote longevity, the researchers said. This delayed aging is likely to occur in other mammals that hibernate, they said, because the molecular and physiological changes are similar."

 

The secret to longevity? Ask a yellow-bellied marmot

Thanks Brian - this is really interesting - and it makes sense in light of much of the evidence in Dean's cold exposure thread and what we know about caloric restriction.

I'll gamble on that being true.

This seems to now be confirmed in hibernating bats as well:

 

Bats show fewer signs of ageing while they are hibernating

Well, now, we only have to find effective hibernation-inducing techniques. Take a leave of absence from work and family, and enjoy the fewer signs of aging.

CR? I'm afraid that's not exactly the same identical thing.
