What did you learn today? Share it with us!

We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.

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

Rules (interactive)


Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.

** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**



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

Your post 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.

Posts and comments 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 non-TIL posts.

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



Rule 7- You can't harass or disturb other members.

If you vocally 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.

For further explanation, clarification and feedback about this rule, you may follow this link.



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.

Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.

I was trying to figure out how many generations could theoretically exist at the same time, so I decided to first check Guinness. Hopefully I did all the math correctly.

Well assuming everyone had kids at 18, and lived to 122, max is 6 generations.

If everyone had kids very young, at 13, it maxes out at 9 generations.

Birth, 18, 36, 52, 70, 88, 106.

Fenceposts are hard to count.

I forgot birth, yeah.

[–] [email protected] 1 points 1 year ago

lol. Yes, they are.

I think OP made an error in stating you had to be 18. The oldest living person ever was 122 (as indicated by Blamemeta). As long as you are allowed a few pre-18 births, you can get to 7 generations). At 15 years old you can get to 8 generations.

You are missing things like this in your calculation.


Under current Pennsylvania law, teenagers aged 13, 14 and 15 may or may not be able to legally engage in sexual activity with partners who are less than 4 years older. Such partners could not be prosecuted under statutory rape laws, but may be liable for other offenses, even when the sexual activity is consensual.

Yeah, OP might be unaware that in the past, it was more common to have a child before the age of 18 than the opposite, specially in rural areas
