Sleep is a tricky thing. Necessary, yes, but how much necessary? There have been times where I don’t need much sleep and I’m so full of energy that sleep is a quick incident to the next adventure.
Nowadays, sleep is an event, a part of my predictable regimented day, a bore. I know if I don’t go to bed by a certain time, my day will not be as optimized as if could be. Such boorish calculation.
Kids need more sleep than adults. I need at least 7 hours to function properly. What ever happened to six? Five would be the best.
