Why Do Some People Like ‘Spicy’ Foods More Than Others?

Some people love spicy food more than others because their bodies feel the heat differently. Imagine your mouth is like a fire alarm: some people have alarms that go off softly, while others get a full-on siren. The spicier the food, the louder the alarm! Capsaicin, the thing that makes peppers hot, makes your tongue feel like it's on fire. Some people just smile through the flames, and others run for water.
