Taste buds wear out every week to ten days, and we replace them, although not as frequently over the age of forty-five: our palates really do become jaded as we get older. It takes a more intense taste to produce the same level of sensation, and children have the keenest sense of taste. A baby's mouth has many more taste buds than an adult's, with some even dotting the cheeks. Children adore sweets partly because the tips of their tongues, more sensitive to sugar, haven't yet been blunted by trying to eat hot soup before it cools.
