So, I was listening Matt Walker's podcast about sleep and how not sleep well decrease our cognitive skills and kill a healthy way of life. You can't un-hear it and the moment you finished these episodes, nothing will be the same. My favorite one is the one that talks about the nap.

Little spoiler: yes, taking naps is good but not for all people. Take naps for some people is harmful. Please, just listen, there are short episodes (~10 min) and each one is a masterpiece.
