Not necessary to do high amounts of activity or vigorous activity to see lower risks: substantially lower risk of mortality when people do at least. Benefits apply equally to men and women, regardless of age, body weight, race. Reduce body fat lower lipids (cholesterol, triglycerides) improve hdl. Leading cause of death in canada ~37% of all deaths. Ex. peripheral vascular disease, congenital heart disease, hypertension. Risks decrease w/ regular pa, healthy diet, no smoking.
