Can you explain why some people have a higher tolerance to alcohol than others?

Alcohol is a depressant, which means it slows down the activity of your central nervous system. The more you drink, the slower your body will work and the more likely you are to feel tired or drowsy. This is because alcohol affects the way your brain works by blocking certain receptors that help control your body’s functions. As a result, drinking too much can cause you to feel dizzy, sleepy, and confused.
