I would have to say Taste?
I was going to go with Hearing but then I would miss out on hearing my children's voices, or hear someone sneaking up on me.
So I'm going with Taste. I'm hoping with the loss of my taste buds, I would grow to hate food and maybe even lose a couple of lbs. Haha
Next week: You're stuck in an elevator with 1 friend, 2 celebrities, 3 items, and NO way out, however, help is on the way. List those 6 items/people to pass the time with.
