Everytime I see someone list "eating" as a hobby, I want to smack them in the head. Given the choice between starving and not starving, everyone's going to choose eating. And eating tasty food whever possible is a nearly-universal part of the human experience. "Fine dining" could be considered a hobby or interest, and cooking certainly is, but eating is a necessity. A hobby is something you do because it's fun, and when you don't have time to do it, you spend your efforts on more important things. A hobby is something you can grow out of or give up forever if you have to.
