There are few rewarding activities.
After a good one, renewed energy and wherewithal seem to provide hours of attentive duty.
As a kid and even in my younger adult years, I rarely took one.
I'm the kind of person who keeps on going, even when sick. The only thing that beds me are body aches from the flu and true exhaustion.
I once heard that Martha Stewart's regimen is getting no more than 3-4 hours of sleep/night. She must have a busy little mind.
You hear about the ways of healthy living, one of them being getting sleep. When your body's at rest, sleep hormones are at work, replenishing, renewing, and rebooting.
I'll never be able to keep a lifestyle less than 6 hours of regular sleep b/c after doing so 3 consecutive nights in a row, my body feels robbed.
So here's to all of you who need to 'shut' down your computers for the night. It's good for you!
