Just in case you need to read this again, exercise changed my life. It simply get rid of the fatigue. Dont take drugs to stay awake, go run half an hour (it really doesn't take more than that to feel tremendous effects).
Definitely. I've recently started exercising more. My bare minimum commitment to myself is to walk a half an hour a day. I regularly do more, but if I only do 30 minutes I don't feel guilty. No matter how long of a day I've had, I'm never too tired to walk for 30 minutes. It's also a good way to build self control through habit.
I would rate my life satisfaction as at least moderate, but is nothing about being alive that could possibly justify the experience of exercise, particularly of running. Given the choice between a lifetime of regular running or death, I’d choose death without even blinking.
You would be missing out on some great experiences. Running is what humans are good at: our bodies are evolutionarily adapted for it. It makes you feel good. Yes, running is hard at first, if you're sedentary. But I can assure you that regular running is considerably more enjoyable than death :)
Indeed, an early morning run or swim will wake you up better than caffeine will.
As can being beaten with a baseball bat or shocked with a cattle prod, but fortunately we’ve found a mechanism other than pain.
I started playing tennis twice a week (would like to do it three times but those are the group times) and I love the difference. Aches have completely gone away, and I feel much fitter overall.
