The point here, IMO, is to make moving - some kind of exercise - part of your daily routine. Unless you have a physical job, try to find some way to stay physical. Bike to work (I know this is often not practical), or go for a walk at lunchtime, or start always using the stairs in the office , or …

It sounds contradictory, but staying physically active really does give you more energy.

To me as a European, posts and comments about US politics can be very confusing. There’s the different interpretation on the word liberal you mentioned. There’s also the fact that the colours are reversed: here red is for the left - socialists and communists - while blue is the liberal right (not so much conservative right, though there are conservative subgroups of the “blues”). And there’s the fact that they often assume familiarity with political events and people unknown to me.

Somewhat related: posts and comments from the far and extreme left are often even more incomprehensible. They seem to have their own language entirely.

Get aired? What does that mean?

I occasionally see similar complaints, and I’m sure it’s legitimate for some users. But personally I don’t get it. I don’t block NSFW content, and yet I rarely see it in /all. When I do it’s usually a bunch at once, but like I said it doesn’t happen a lot.

The only thing in /all that used to bother me is the sports stuff, but by blocking a single community that’s mostly gone now.

The same image is shown to a lot of people. If a majority of people click on the same things, that is assumed to be the correct answer. And it is added to the training database. Occasionally you’ll get one that hasn’t been shown to enough people yet to know for sure. For those, they’ll usually accept any answer, even wildly incorrect ones. The thing is, you as a user never know which ones they already know and which they don’t.

In my experience, immature posts are made by people well over 13.
