We still don’t know the limit. As I often say, there is no law of physics that requires either senescence or mortality. Indefinite health and life is, in theory, a solvable problem.
[Afternoon update]
A commenter points out this recent article. Yes, I’ve discussed this with Gary, and it’s currently his focus, not space. Because none of us are getting any younger. BTW, the company name is pronounced “ocean,” I think. And yes, we should be trying to get Congress to tell the FDA to recognize aging as a disease to be treated, and not simply inevitable.
I’ve never paid much attention to him, but he seems to have been quite a character. Here’s a foreword he wrote to a book in defense of a guileless restaurant reviewer in flyover country.
The latest, and it looks promising. Humans aren’t rodents, but no reason in principle we shouldn’t be able to do similar things.
[Tuesday-evening update]
Intermittent fasting seems to help. I’ve been doing this as part of my weekday routine for a while. I go all day without eating until dinner time, other than coffee in the morning, but it’s mostly out of convenience rather than for health reasons. I’m glad to hear it might be good for me.
This seems like a very promising approach. First dogs, then use the revenue to do clinical trials on humans. I’m holding up pretty well for my age, but I’d really like to set the clock back.
[Update a few minutes later, after reading]
I’d note that one of the “diseases of aging” listed is diabetes. I think it’s pretty clear at this point that this is mostly a problem of poor diet, based on decades of criminally terrible nutrition recommendations, and can largely be reversed by simply going keto. In fact, they’ve found that it can even be an effective treatment for Type 1 (and it was, prior to the development of insulin).
It may aid in the regeneration of stem cells. I do this almost every day. Not quite 24 hours, but I often don’t eat from when I go to bed until dinner the next evening. Other than morning coffee, which I don’t think would count, given its utter lack of nutrients.
