Well I guess everyone has to find what works for them. I brisk walk the dog 4km up to Camp Lookout and back, 2 or 3 times a week. My BP before is around 140 / 70, down to 115-120/60 after 1 hour. I don't eat fast food (maybe lumpia once a week) but I do enjoy a drink, regular but moderate ( I guess that's another subjective opinion).
Anyway, I guess everyone has to find what regime works best for them.
