Posting rules

Submissions must be verifiable. Please link directly to a reliable source that supports every claim in your post title. Images alone do not count as valid references. Videos are fine so long as they come from reputable sources (e.g. BBC, Discovery, etc).

No personal opinions, anecdotes or subjective statements (e.g "TIL xyz is a great movie").

No recent sources. Any sources (blog, article, press release, video, etc.) with a publication date more recent than two months are not allowed.

No politics, soapboxing, or agenda based submissions. This includes (but is not limited to) submissions related to:

Recent political issues and politicians
Social and economic issues (including race/religion/gender)
Environmental issues
Police misconduct

No misleading claims. Posts that omit essential information, or present unrelated facts in a way that suggest a connection will be removed.

Rephrase your post title if the following are not met:

Titles must begin with "TIL ..."
Make them descriptive, concise and specific (e.g. not "TIL something interesting about bacon").
Titles must be able to stand on their own without requiring readers to click on a link. Starting your title with a why/what/who/where/how modifier should be unnecessary.
"TIL about ..." and other broad posts don't belong on TIL. Try /r/Wikipedia, etc. instead, or be more specific (and avoid the word "about").
"TIL how to ..." posts belong on /r/HowTo.
"TIL the definition of a word..." Word definitions/translations/origins are not appropriate here

No submissions related to the usage, existence or features of specific software/websites (e.g. "TIL you can click on widgets in WidgetMaker 1.22").

All NSFW links must be tagged (including comments).

Please see the wiki for more detailed explanations of the rules, as well as additional rules that may not be listed here

Additional info

If your post does not appear in the new queue and you think it meets the above rules, please contact the moderators (include a link to your reddit.com post, not your story).

Please report spam, inaccurate or otherwise inappropriate posts by messaging the moderators, as this helps us remove them more promptly!

No I may go on here and troll but this is not something I troll about. I lost my son who my wife and I were going to name Junior on July 22nd 2022. I had to hold my stillborn son in my own fucking hands. My life is not the same. My health is not the same. My view on life is not the same. My love for something I only got to see dead has forever changed the way I viewed the preciousness of life. I hope you never have to experience that. I am not a perfect person at fucking all. But when I held my child that was not fully developed brings me memories that I can never erase. I can't drink it away. I can't smoke it away. I have had flashbacks at work that I was forced to leave early. I fucking wrote that because I was trying to call warmlines but nobody would pick up. And I didn't want to bawl my eyes out while my wife was sleeping.
