The news item this morning from Boston about the "near-universal" health care made me think about wellness. There is difficulty incentivizing behaviour.
As with other things in life, there are probably as many reasons for not taking care of yourself are multitude.
One thing that could contribute would be having your gym count days in attendance each month and granting credit for it in some way. The gym could use RFID on membership cards and you wouldn't get credit if your stay is under 45 min. In essence, you get paid for attending the gym.
