The power went out the other night around one in the morning.
Back in the day, I would have overslept my alarm, I wouldn't have woken up.
I know I'm getting older because I woke up (around an hour before my alarm was set) and reset my alarm clock. I can't remember the last time I overslept an alarm. I think it is getting older, and getting a good night's sleep on a regular basis (i.e., going to be before 1 a.m. on nights I have to work the next day).
I am still not a morning person, and will probably never be one. It's just a sign of aging (from my understanding) to wake up multiple times during the night and not need as much sleep.
