Better to Laugh

Why is it that I am always exhausted, but I don’t sleep?  Could it be that my brain is usually focused on so many things that when I get some time to myself I don’t want to spend that downtime unconscious?  Or maybe it is because I keep getting a second, third, fourth wind?  My mother always says that I wouldn’t go to bed when I was younger because I was afraid that I would miss something.  Well, I don’t know what I am about to miss, but I have to get some shut-eye.
