Exercise tends to help.

Unless you also got PEM with your long COVID, then exercise makes it a lot worse. Bro science is dangerous.

“Exercise is healthy” is very, very far from “Bro science”.

Scientists may have found mechanism behind cognitive decline in aging, but there shall, in that time, be rumors of things going astray, and there shall be a great confusion as to where things really are, and nobody will really know where lieth those little things with the sort of raffia work base that has an attachment that one may confuse with clickbait.

I'm having a very hard time understanding this comment. Perhaps my cognitive decline has begun.

Update: I see I should rewatch "Life of Brian".

"Exercise helps post-COVID cognitive decline and insomnia" is absolutely bro science, and especially since it can make the whole situation much, much worse.

Immortality raises a lot of ethical and philosophical questions that we will need to tackle if it ever becomes real. For example, if you live 200 years, how much would you remember of your first 30 years of life? Will that 200 year old person still technically be the same as the one that was born if he hardly remembers anything?

No it doesn't. I'm a good bit younger than 200 and barely remember large portions of my earlier life already. What's so special about 200 that makes it any different?

In another comment I spoke about how many more people are able to reach 60+ years of age, and that the amount of people living longer have exponentially grown. Our world population reaching another billions milestone at faster timeframes. Scarily, life expectancy was always at around 20-30 years for a large portion of history for humans.(most who reached 15 years of age were capable of living to 50 years albeit they were considered to be outliers) Around neolithic times, we had moved towards increasing population density and promoting growths. This time period was odd as it lowered the overall life expectancy because there were more humans that died from other methods as lifestyles changed from hunter-gatherer to more sedentary lifestyles. Hunter-gatherer lifestyles required loads of land for a single human to survive, which the neolithic era had been able to fix with the introduction of farming. Due to density, more people started attacking one another for variety of reasons and heavily relied on farm crops to sustain increased human populations. Societal growth of centers such as towns and cities then countries continued. Excluding many outliers, life expectancy only started to rise in the 1950s and has kept further increasing past 50+ years and 60+ years.

So yes there is something special about reaching 200 years of age. As it will singal a milestone no other human has ever reached from all of history. On the other hand, life expectancy growing at an alarming rate is putting a lot of strain on resources and land availability.

That would change the title into your reading. The title is literal. Pharmacological treatments are proposed - for humans.

If one added that specification, it would change the meaning that David Kelly seems to have intended. (It would change it to what the poster understood.) Kelly does not seem to restrict the matter to mice, as Uli Bayer does not seem to.

> This isn't what the title says or implies

It is what the submitted divulgational article from the University writes, and the title follows.

At this time, a friend shall lose his friend’s hammer and the young shall not know where lieth the things possessed by their fathers that their fathers put there only just the night before around eight o’clock.

Honestly, this is basically it. The organisms that supposedly don't suffer from aging, are probably just better at accounting for entropy.

What does that mean?

Over time things break down and don’t work as well. Some organs cope with this better than others. This is how I read it.

If you take a lot of vitamin d, make sure you also take vitamin k. Just a random source here because I'm too lazy: https://www.balancedwellbeinghealthcare.com/are-you-taking-v... > Because vitamin D is so good at improving calcium levels, by taking it alone you could be working to increase the calcification of your arteries instead of strengthening your bones so make sure to include K2 in your vitamin D supplement re…

Do you have any recommendations for K2? A generic brand would be okay? Thanks

I just get D3 and K2 together and seems to work pretty well

A cell still needs its DNA (to make proteins among other things) even when it is not dividing.

They asked about “compared to the rest of the body” and I was explaining (to the best of my knowledge) why it doesn’t work the same.

I know
