I'm totally getting old

Last night I went to bed at 9:00. I was dead asleep by 9:40. I woke up at 7:15 when the alarm went off, turned it off, and slept until 9:08. It was amazing. It felt fabulous. And then, to top things, I took an hour and half nap this afternoon. I'm not sure what is wrong with me, but I am pretty sure it is because I am getting old.
