For many people, coffee is a standard part of every single morning. And most people know not to drink too much of it. But what would happen if coffee became the only beverage you drank?

The YouTube channel Life Noggin decided to investigate what would happen if you only drank coffee. In the short-term, you'd probably feel sick and have a number of minor neurological problems. In the long-term, it can actually hurt your heart health and hypothetically land you in a coma.

Take a look above and see what they have to say.

So, maybe you'll switch to decaf next time?
