This is an interesting article. I don't really trust online researches these days but having a hobby does make one happier. And I'm not just referring to Gunpla. It could be anything you like to do. It just has to be something you enjoy doing and derive satisfaction from it. You don't even have to be good at it as long as you spend quality time. Coming back to this hobby, yeah it's a lot of fun. I have been doing the same thing for over a decade...
