No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here. This includes using AI responses and summaries.

Asking this because none of the 38 year olds I know are taking any medications and they look really young

This article is talking about a correlation they see between the natural lifespan of animals in the wild and then applying it to humans and getting 38. Lifespan in this context is like the lifespan they give for humans currently which is 73 world wide. This is a statistical average that takes into account people dying at a few months and at 102. It does not say anything about health or that the we have some sort of genetic deathclock. What it is likely showing is when we are sorta officially getting old. When you don't heal as fast and your reflexes and such may be not at top form. and that is not necessarily 38 as its unclear how the number is derived vs methlyization. The 38 number would be for a state like animals. Before domestication, before farming, etc. And again its a stastical average and a particular animal can live much longer be it wild animal or when homo sapiens were. Honestly I could definately tell a loss of for lack of a better term lets call "youth". Basically what I had going in to 30 was gone by the end of 30 and a new normal arose. If you look at it you can sorta see how we start as babies and pretty much you get more powerful as you get older through your first third of life so about 30. Next third goes down slowly but by and large maintains decently. Last third or after 60 you get things falling off faster and its hard to maintain like before. So figure in a random fight of a 35 year old and 55 year old the 35 may have an advantage but you would be a fool to think its a slam dunk. 25 vs 65 though and yeah the 65 may win but I think some luck will be needed. Again this is assuming some sort of typical. If the old guy is the mighty atom and the young guy is some super pussy like donald trump in his prime then its a different story.
