At least three - in some people. Regular exercise has been shown[1] to reduce the signs of depression in some people (but, obviously, not others). From what I know of hypertension (not much), it's more of a disposition - if you treat yourself poorly, and you have a disposition towards it, you might develop it later in life. Exercise and diet, of course, are preventative - but not a cure; once you are diagnosed, it's like a warning sign from your body flashing "hey you, be careful, you're hurting me!" And it's not just regular exercise, a balanced diet is a must. If all you eat is corn (factory farmed meat; processed foods; just about everything cheap in the grocery store) - but you run on a treadmill 30 minutes a day - you're still going to put on weight.
