If health was important to them they wouldn't be sat at a PC 40 hours a week, probably more than that with some of their jobs and time spent outside of raiding hours on the game. You should probably get a personal trainer in as well, maybe a warrior?
We actively encourage people to exercise at least 3 days per week, sitting at a PC 40 hours/week is no different than most middle aged women watching soaps for 5 hours a night. At least we get something out of it.
