I just realized why I would hate to have my sense of taste and smell to go away.

I like cooking and making things taste good...smelling the spices and guessing how to make things taste the way I want them in my head or how to improve something or to figure out what is missing.

That's why I would hate losing this sense so much. I think I'd almost rather lose my sense of hearing or sight rather than this, although those are usually considered the things people would not want to lose the most.
