as a preliminary step to getting a physical by a family practice physician, stop at your neighborhood pharmacy and get your blood pressure checked. Most of them have an automated setup where it's done, and it can be very enlightening. If the benefits where you work are as good as you say, they must cover routine preventive medical checkups. Another aspect to consider is your life outside of work - do you get healthy exercise? jogging, long walks, bike riding, swimming? Every considered Tai Chi or Tae Kwon Do classes ?
