I had a medical surveillance review this morning as a part of my HAZMAT training for a project I'm working on. Among the battery of tests they completed one included my blood pressure (107/67) and heart rate (53) which they told me was low. I asked if my lack of exercise program was working and the doctor told me, "Absolutely." He also said that if I exercised it might skyrocket to 150 or something, so I told him I'd be on the safe side and stay on the couch.
