genuine question: why would someone want to live longer than the average? Edit: I ask because I personally don't see a reason to stay alive while people I love are dying, I don't see a reason to stay alive in an already fucked up planet, while we empty all the resources, etc. But you guys are so smart, intelligent and clever, why even bother.

Who wouldn’t want to be healthier than average at a given age?

The article states effectiveness requires taking the drug as a young adult, precisely the time most people are not thinking about mortality.

I’d beg to differ. In the modern social media age youths are getting a lot more vain.

Teen boys are doing skincare routines.

So historically, I’d agree, but now that everyone can be a minor celeb in their own circle I think the youth are more focused on aging.

Curiosity? See where this ride is going and maybe have some hand however small to steer it?

the gist of it

""" The scientists have tested different time windows of short-term drug administration in fruit flies and found that a brief window of 2 weeks of rapamycin treatment in young, adult flies protected them against age-related pathology in the intestine and extended their lives. A corresponding short time window, 3 months of treatment starting at 3 months of age in young, adult mice, had similar beneficial effects on the health of the intestine when they were middle-aged.

“These brief drug treatments in early adulthood produced just as strong protection as continuous treatment started at the same time. We also found that the rapamycin treatment had the strongest and best effects when given in early life as compared to middle age. When the flies were treated with rapamycin in late life, on the other hand, it had no effects at all. So, the rapamycin memory is activated primarily in early adulthood”, explains Dr. Thomas Leech, co-author of the paper. """

And here I am wondering what the cutoff is for middle age...

It's not only "living longer" as a whole organism, but also your individual organs living longer (that ultimately impact aging). Take ovaries for example: Menopause causes major health problems (osteoporosis, cardiovascular disease, etc) for women and women now spend on average more time post-menopause than pre.

that's a nice catch, thanks!

This isn't just about extending how long you live but also the reduction of disease. That's something that seems highly promising about some of these treatments

The bigger story with rapamycin is that the mechanistic target of rapamycin (mTOR) plays an absolutely crucial role in major diseases of modern civilization. One of the ways to inhibit mTOR for free is to simply stop consuming nutrients for extended periods of time.

How frequently and for how long must one fast to see this?

When somebody asks about what is the next big thing, I always think on anti-aging. If you think that you don’t want to live forever, imagine that today when you arrive home you find a note saying that you will die exactly 1531[^1] days from today. How would you feel?

With that said, I would stay away from miracle drugs, because no two human beings have the same physiology. But that’s not an unsolvable problem.

[^1]: It’s a random number to “erase hope”. Not knowing when we are going to die keep us slightly hopeful and perky, our mind away from the problem.

> One of the ways to inhibit mTOR for free to simply stop consuming nutrients for extended periods of time. What is an extended period of time in this context? I happen to consume all my meals within seven hours every day and only drink water in between. Would that help? (Not doing this for health reasons, it is just a habit.)

This [1] study was pretty thorough on different fasting lengths. They tested 1422 patients for fasting lengths between 4 and 21 days, with a maximum calorie consumption of 200-250kcal and a moderate-intensity lifestyle program.

It concludes that all fasting lengths are beneficial, and are likely going to result in a) reduction in weight and waist circumference, b) beneficial effects on blood lipids, regulation of sugar and other blood-related parameters, including lower blood sugars and higher ketone body levels, c) an increase in physical and emotional well-being and absence of hunger, d) a high probability of decrease of pre-existing health-complaints, e) very limited chance of side-effects.
