lol this is literally all false. toys - no, the gi-joe does not improve anyone's mental capacity. sports - are mostly played because people all over the world spend billions per year watching them. the athletes who play them end up with a damaged body, permanent injuries, and lots of back problems after 30. playing poker - the old man losing his house in vegas is training. gotcha. now, bitcoin mining - people want to do it, people are paying money for the energy to do it, and that's all you need to know.
