Sleep

It really is a funny thing, isn't it?  Sleep.  A simple concept in its most basic form, but so complex when you consider everything that goes into it.

Simple: Our bodies run down and need a recharge.

Complex: No one in the scientific community can agree on exactly WHY we sleep.  They throw around theories of a lack of ATP, the brain needing to do some housekeeping, and that our cellular system forces us to shut down so it can do some renovating.

So why is it that some people can run on 5 hours of sleep and be as productive and happy as others who absolutely must get a minimum of 8 hours of sleep?  Do the 5-hour people have faster cells that can strip the dead stuff and rebuild new stuff?  Or does "slow and steady" win the race?

And why is it that we need to sleep to deal with all the stuff that goes on in our brains?  We dream to filter and process.  Why can't we do that during the day?  Is it the whole concept of "we can only access about 10% of our brain's capacity?"

...It is 5:30 in the morning, and I'm pondering the ins and outs of sleep.

Yeah, I'm one of those freaky 5-hour sleep people.

Don't hate me.  It ain't always that much fun.
