Does sunscreen expire?
Is that leftover sunscreen from last summer still OK to use? Maybe. Sunscreens are required by the Food and Drug Administration to remain at their original strengths for at least three years, and some products include an expiration date indicating when they're no longer effective. This means that you can use leftover sunscreen from one year to the next, up to that expiration date. Keep in mind, though, that if you use sunscreen as recommended — generously and frequently — a container shouldn't last long. Learn more from Dr. Lawrence Gibson, a Mayo Clinic dermatologist.

Does atrial fibrillation run in families?
Atrial fibrillation is an irregular and often rapid heart rate that can increase your risk of strokes, heart failure and other heart-related complications. Atrial fibrillation that is inherited is called familial atrial fibrillation. It has been associated with changes in certain genes in a small number of cases. Although the exact incidence of familial atrial fibrillation is unknown, recent studies suggest that up to 30% of people with atrial fibrillation may have a relative with the condition.
