Reply to comment by kurrpy in TIL that tularemia is an infectious disease that can be contracted by “inhaling particles from an infected rabbit ground up [by] a lawnmower”. by krisalyssa

I don’t. We were watching an episode of Alone, where one of the contestants caught a porcupine but discovered upon cleaning it that it was infected with tularemia. I was curious if the meat would be safe if properly cooked, so I looked it up.

And that, kids, is how I met the phrase “the only place in the world where documented cases of tularemia resulted from lawn mowing”.

Reply to comment by ThatFaultyGamer in TIL that children born earlier in the academic year have a higher chance of participating in upper echelons of sports or academia. This is known as the Relative Age Effect. by ThatFaultyGamer

Keep in mind that this article is talking about how kids born in the later part of the year are more likely to be diagnosed with ADHD, not that they are more likely to have ADHD. When compared with other kids in their grade they may seem less mature and less able to focus because they are developmentally less mature and less able to focus. This comes out in the wash later in life. Some of the kids will of course actually have ADHD, but some were just acting younger because they were younger.
