Everybody's doin' it. There must be some reason.
I've been programming for 30+ years in more languages that I can count. I've been weaving (as in cloth) for several years. Weaving and computers mix well. My newest obsession (if you don't count the bike I just bought) is learning to play the upright bass. My even newer obsession is contra dancing.
I am also "the kind of person that keeps a parrot" (see the Mark Twain quote)
