Justin Morgan owned a bay colt born in 1789, he named Figure. Figure's ability to outwalk, outtrot, outrun, and outpull other horses was legendary. After Justin Morgan's death, Figure became known by his former owner's name, the Justin Morgan horse.
Part of that may be because our sense of taste is slowly dying. Sadly for the rest of us, our physiology is working against us on nearly every front. As we age, our taste buds stop regenerating, and our sense of smell dulls. An average adult taster might have 10,000 taste buds in his or her mouth. A supertasterâone of those 15 to 25 percent of the population whose tongue is extra sensitiveâmight be gifted with twice as many. A non-taster, meanwhile, might have to get by with half the norm.
How exactly do your taste buds work? Well, stick out your tongue and look in the mirror. See all those bumps? Those are called papillae (say: puh-PILL-ee), and most of them contain taste buds. Taste buds have very sensitive microscopic hairs called microvilli (say: mye-kro-VILL-eye). Those tiny hairs send messages to the brain about how something tastes, so you know if it's sweet, sour, bitter, or salty. The average person has about 10,000 taste buds and they're replaced every 2 weeks or so. But as a person ages, some of those taste cells don't get replaced. An older person may only have 5,000 working taste buds. That's why certain foods may taste stronger to you than they do to adults. Smoking also can reduce the number of taste buds a person has. But before you give taste buds all the credit for your favorite flavors, it's important to thank your nose.
