Your husband doesn't have to be you. Just because you have a hobby you are interested in doesn't mean he needs to have one. Video games, tv, beer, and bedtime are sometimes hobbies unto themselves.

That said, I always try to take an honest interest in at least KNOWING about my girl's hobbies/interests/job etc, whether or not I participate. I definitely have to tune down how much I talk about fishing and reptiles because I know that my girl isn't as interested in it as I am, but she is happy for me when things are going well in those hobbies
