Why Do You Need to Sleep?

When i started my life, this is a question i've been interested in for a long time. Why? Right? Why do you need to sleep? And why is an interpretation, right? We can say, like coke, this is why it happens. But what we can experimentally beally show is, like, what happens, right? Like how things go? When i started the lab, a postvall came to my lab. Alex vacar h was just ideal for this. The first thing that really surprised me was that when you deprive animals of sleep, they crash, they die prematurely. This is in flies, and it was very reproducible when they die.
