I'm 64. Kids are grown.

Most days, in bed by 9 and up by about 4 am. So 7 hours. Sometimes a little more. Usually get up an hour early and go to the living room and sleep in a chair for the last hour.

I have some back issues and use an adjustable bed and sleep upright sort of for the first 1 to 3 hours. Then on my side. When I go to the chair it is just right for upright sleep.

I go to the gym at 5 am and need 30 mins to an hour before doing my gym routines.

At 64 I love a good nap. At work at lunchtime for 10-15 minutes. On the weekends for 20 - 25 minutes. Naps are always upright just like a meditation sitting posture.
