Sleep - enough already

Seems that Americans are proud to announce that they can "get by" with only five hours of sleep each night. Why would they only get five hours let alone be proud of saying it?
It is recommended that we get a full eight or nine hours of sleep every day. This length of time allows your body to get enough rest, your mind to get all it's processing done, and your soul to have time to play without boundries. Unfortunately, most people don't take the time or cannot make the time to sleep eight or nine hours a day. I guess I can understand,(to some extent) why those who cannot take the time because of having multiple jobs to make ends meet. But that is another subject to blog about. Why do they need to work more than one job?
I digress, what is so hard about taking care of ones body? It doesn't take willpower to sleep like it takes to keep yourself from over eating. It doesn't take discipline to sleep like it takes to exercise five or six days a week. It doesn't take reminders to sleep like it does to drink eight glasses of water every day. It doesn't take a seven day pill organizer to sleep like it does to take all your medications and supplements. Seems to me the easiest of all those "healthy" things we are all charged with doing is the sleep thing.
If people got more sleep they would likely be less irritable, less frustrated, less...oh I don't know...TIRED!It is really simple don't you think, when you really think, hard and serious? Come on...give me any good reason why we can't at least get some more sleep?
