You registered in february 2018 and you call me naive? That's a joke?
There is no correlation between account age and naivety, just like there is none between hunger can "bad cells".
Hope you've understood the sarcasm and I don't have to link to the message
although it fits the topic perfectly...
It's just the "theory" that won the medecine Nobel prize of 2016 ...
Hunger stimulates self-destruction
By eliminating damaged proteins, autophagy is critical for counteracting the negative consequences of aging. Even more important, Wollert said, autophagy enables humans to cope with scarce food sources - in other words: starvation.
"In times of hunger, a cell will enclose part of their cytoplasm, digest it and thus regain important nutrients," Wollert said. "This way, a cell can uphold its vital functions."
Wollert compares it to what some people call going on a diet. With less food than usual or none at all, people get thinner but stay alive.
"Autophagy starts every time you have not eaten for more than 12 hours," said Rupert Langer, of the Institute of Pathology at the University of Bern. If researchers shut down the process of autophagy in lab animals and then don't feed them for a while, those animals die quickly, he added: "They can't cope with the stress of starvation."
