Aging is when Christmas and Easter come and you're more excited about getting a chance to sleep in than you are about waking up at 4 or 5 am to see what Santa or Easter Bunny brought.
Eh it's probably just hormones, but I have to say I like sleeping. Someone mentioned to me that Posner sleeps only 4 hours a night and I was rather horrified. I guess I ain't no Posner. I can console myself with the fact that I'm more like Einstein, who was a 12-hour man.
