Research shows that lowering cholesterol using a variety of approaches–including medications and diet–can lower the chances of having a cardiovascular event, including a heart attack.

The belief that women should avoid exercise or athletics during their menstrual periods, because it can affect performance or increase the risk of injury, is not necessarily true.

Teens don’t exercise enough, and with a third of U.S. adults classified as obese, it’s important that exercise is encouraged in children and teens.
