You Name It, and Exercise Helps It

“The single thing that comes close to a magic bullet, in terms of its strong and universal benefits, is exercise,” says a scientist at the Harvard School of Public Health. It has protective role for heart attack, stroke, hypertension, diabetes, obesity, depression, dementia, osteoporosis, gallstones, diverticulitis, falls, erectile dysfunction, peripheral vascular disease and 12 kinds of cancer. But what if you already have one of these conditions? Or an ailment like rheumatoid arthritis, multiple sclerosis, Parkinson’s disease, congestive heart failure or osteoarthritis? How can you exercise if you’re always tired or in pain or have trouble breathing? Can exercise really help?
