I have a neighbour who's in his 60s. Blood pressure was of the charts while in his 40s. The guy was cycling to work everyday (and thought that was enough exercise) and was living a stressful family and work life.

Doctor never prescribed any drugs but told him that he had to start exercising. Signed up for judo class. He couldn't believe the amount of exercise he got from the warm up alone. Been doing judo 3 days a week for 20 years now. Haven't had any heart or blood pressure issues since.
