How is that possible?

I once slept for about 30 hours when I got sick with mono, seriously messed with my head

If done that Once when I was sick and another time after I played 16 hrs of full court basketball with only 2-3 min breaks between pickup games. After a 20ish game win streak we all decided we weren't going to stop until we lost, so after the rec closed we went to the outdoor court across the street and continued. The streak got up to like 35-40 before we finally lost.
