From the BBC website list of 10 ways to beat the blues:

7. Take up a lifetime hobby

"Unless we have an interest and unless you have work - play work or money work - an activity that means something to us, it's hard in our society to feel relevant or useful," says Mr Hodson.

It helps if the pastime we choose is "something that absolutely takes you out of yourself.

"If you only dwell in your own head you're going to be miserable."

Our hobbies should, ideally, be something we can take with us through life and connects us to our earlier selves. "I stopped playing squash when I was 40," cautions Mr Hodson. "The idea of picking up a squash racquet now is fanciful," he admits.

I think this means that model makers should all be stress-free and happy. This in turn will lead to a long life, perhaps long enough to build all the kits we accumulate in cupboards !
