Yeah I do that too. When I get really enthusiastic about something, I can talk about it for hours. So, it exists.
I was told it is apparently an ADHD thing. Because some people I used to meet, did the same thing, about their favorite topic each. So, it’s an ADHD thing, apparently.
But I’m glad you can bring up the mental energy to talk about a topic for a long time! That means you’re healthy :-) (imo)
I’m sorry for anybody living in the US right now. The only hope is that it will get better, in the far future, when all those billionaires will have transported themselves to Mars. Then you may find some peace, I guess.
