In two US studies, doctors have found that 15 minutes of laughter a day is good for the vascular system. They found that the blood flowed more freely in 9 out of 10 people while they were laughing, with average blood flow increasing some 22 percent. The physical benefits of laughing were similar to those people get when exercising, without the aches and pains. But -- we're not off the hook -- doctors say that we should continue to exercise at least three times a week. (story)
