When an activity is good enough to do, it is good enough to do in excess. That's my motto!
Aircraft, collecting old military rifles, traditional muzzle loaders - it only is acceptable to go overboard with the interest.
I don't have the time or patience to build model aircraft anymore, so what you see are diecast models that either are pre-built or just required popping on wings or stabilizers. 1/18 scale versions hang from my ceiling. My wife says that I have the attention span of a schizophrenic hummingbird and that is not a characteristic conducive to building models.
Nowadays, my flintlocks and percussion firearms have taken over from all my other interests. My 98K Mausers, Arisakas, Swiss K31, Finn M39, M1 Garands, M1 carbines sit forlorn and abandoned as I go off to the range with the sidelocks. Sad, but true.
The cat, Rusty, is a specially trained guard cat who protects my firearms and accoutrements 24/7. When he isn't doing his duties, he is draped over my shoulders as I type - great during the winter, but a little warm during the summer.
