I just naturally wake up on workdays at 6 am and sleep in until 7 to 7:30 on the weekend. I go to bed by 10 pm and normally stay asleep for the night. I may wake up once, but don’t have an issue falling back to sleep. H has some sleep issues and wakes up once or more during the night and sometimes can’t fall back to sleep.
My mom is someone who has always been able to sleep late and can easily sleep 10 hours or more a night even at 81.
