Make Gym Memberships tax deductible.

I feel that gym memberships should be tax deductible and/or eligible to submit to flex spending for re-reimbursement. If we are serious about people getting healthier then we should give them an incentive to do so. Perhaps there should be a rule that you have to prove you go to the gym at least 3 days a week in any given month to prevent people from just getting gym memberships to write off on taxes and never go. I believe more people would go to the gym and get healthier if they were able to reduce their tax burden at the same time.
