I was introduced to the hobby by watching my older brother back in the "Golden Age" (1960s). I built a lot of models (cars, ships, planes) as a kid. Although I "graduated" to 1:1 cars as a teenager, I never lost my love of models. It's been a central part of my life since I built my first one at age 6. As Jordan191 noted, it helps to keep my mind occupied in a positive mode, even when I can't actually get to the workbench. Although there have been periods of time (months, years) that the real world kept me away from the bench, the projects kept on going in my head. I also like the fact that this is a good wholesome hobby that the whole family can get involved in if they choose to do so.
