Heart rate and age are necessary components in estimating your heart’s response to exercise. Heart rate is the number of times your heart beats per minute.

Stomach bugs are common in kids. The stomach flu, medically known as viral gastroenteritis, is an infection of the intestines. Although most people catch the stomach flu by ingesting contaminated food or water, you also can pick up this infection by coming into contact with an infected person.
