A thought about hobbies/craft

I have a whole post about the differences in hobbies/crafts I participate in up in my head somewhere, it'll probably get posted when I start being disciplined as a blog writer. :P One thing, though, that strikes me as interesting—there's so often the assumption that the particular hobby being discussed is the only one you have. My writing acquaintances often talk about 'write every day', 'don't complain about not having time,' etc. Same from drawing people; similar stuff from photography people, even though that hobby is more business oriented (at least in my circle of people, which admittedly focuses on model photography.) Even knitting people often talk about knitting All The Times, although this is the hobby that seems least isolated; I know lots of knitters who also crochet, weave, spin, etc.

(I'm not saying everyone in the hobby does this/has no other hobbies/ etc, it's more of a general impression based on my experiences and social circle.)

It gets me to wondering: do most people only have one or two hobbies? I have this impression that they do, but, um, clearly I do not. I pick up a new hobby every 1-2 years, on average. (In addition to the ones I've mentioned here, I also sew, play video games, and ride horses. I plan to learn to spin, weave, dye, and learn to shoot films at some vague point in the future.) I don't watch TV much—when would I have the time? :)

Anyway, if you have a hobby or two or several, post them here? It will be a very unscientific poll. And do your hobbies have the impression of being an exclusive hobby or are they full of multi-hobbied people?
