We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Sleep. It is amazing, as MissT said. It is also critical to good health - and not just IMHO.
There seems to be a 'heroic' aspect to sleep deprivation - you always hear someone say "I only sleep 4 hours a night!!". Well, you can train yourself to do that (talk to a Navy seal), but are you actually working at full capacity when you are NOT sleeping? No you are not.
If you need an alarm to wake you up, you are not going to bed early enough, or you are not sleeping when you do get to bed. Make the room dark and cold, snuggle in and relax the mind.
Sleep. Longevity and health-gevity as Peter Attia, M.D. says. If you don't know about him, go look him up. He is a remarkably knowledgeable person. I'm a mathematician/statistician and he can give me a run for my money.
Yup. I stay in bed but I only sleep four hours more or less. Wasn't always that way but I am 74 and I guess that has a lot to do with it. I'm not a worrier and I don't have a problem falling asleep. I simply wake up a few hours later and stay awake for a few more hours. Sometimes I get back to sleep but rarely more than four maybe five hours on a good night.
I have thought about getting up and making good use of the time but it would disturb my wife. So instead I usually build something in my mind. It passes time and these kinds of things interest me so it is better than cursing the darkness.
