Taste

Taste buds or taste receptor cells in the tongue allow a person to taste the different flavors of the food he or she eats. An average person has around 10,000 of these cells, which gets replaced every week or two. As a person gets older, cell replacement is much slower and some of these cells do not get replaced anymore. An older person may then have only about 5,000 working taste buds.
