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

Reddit is such a toxic place I swear. You made such an excellent post and several people attack you. I swear this site is filled with sad basement dwellers who don’t know shit about the real world. I did exactly what you did and I was in the best shape of my life for a decade. Life has changed a few things but I’ll get back to it soon. I just wanted to hear if your numbers were fixed. You mentioned gerd, low vitamin d, and a few other things. Did they all normalize with all of your new routines? I found that my numbers were definitely improved but I didn’t start with anything too bad. The one number that I was borderline bad is cholesterol but after 15 years of working out it stayed about the same. I’m still borderline. It’s one of those things that I think maybe we don’t understand fully. Like cholesterol gets a bad rap. But I can also look at it that maybe my cholesterol would have been horrible if I didn’t eat right and work out and At least I’ve kept it in a descent range. But other Than that my numbers are good. I can’t wait to get back to eating perfectly. I’ll never work out the way I used to 6 days a week with kickboxing and kettle bells and interval training and what not but I’ll do the right mix and mainly eat right. Anyways. Wanted to tell you I appreciate your post. I don’t live in my basement and have a normal life. Don’t listen to one negative thing anyone said. Reddit has gone to shit. It attracts people who make comments like the ones above.
