Today I want to talk about sleep.
You know life on earth is adapted to the rotation of our planet, and we have known for many years that we, as humans, have clocks that work with this regular cycle of the the planet turning around itself. So we have these body clocks but how does it work? That’s not something that we’ve really known. I’m from Sweden and in Sweden we have the Nobel Prize, I’m not sure you know about it but here it’s a big thing and I usually hear about it every year and there are all these prizes for scientists who’ve done things that most of us don’t understand.
