Wait till you are 35-40 years old. Guaranteed, staying up until 6am is going to be a challenge. Also, getting up around 6am is easier because you gotta pee.
I hear that. I stayed up until 1am playing pc games and now my shoulder hurts like I spent 6 hours arm wrestling a bear. I'm learning about RSI in realtime...
I'm 38 and am a night owl. I work a 8-5. During holidays I drift HARD to staying up late and waking up late. I'm in the Eastern time zone and it's 12:46 a.m. EST. FML.
It's a bitch when I have to go back. I've been a night owl since high school. My mom is one. Everyone I associated with in high school was one. In HS I worked a pizza job and regularly closed the store late at night and stuck around to shoot the shit.
I was a night owl as well until around the age of 25. After that I just couldn't do it anymore. And I guess it all depends on your definition of night owl as well. Back before age 25 I would go from work to staying out all night to showing up back at work the next morning with zero sleep or watch movies and play video games till very late without any issues. These days I can't imagine going out like that unless it's a festival, but the last one I even went to was 2016. I am still up till about 1am just because with kids I like to have the 2-3 hours of peace to do what I want to do. It's about 1am when I dose off. It's not like I am going to bed at 10pm, I just can't stay up all night like I used to.
I’m in that age range and my insomnia has recently returned. Like when I was younger, I can’t go to sleep until dawn - almost like the daylight makes it safe to sleep or something? Weird as hell. It’s currently gone 2am and I’m not remotely sleepy. I’d been nocturnal for sure if it was remotely feasible/socially acceptable.
On a whovian note: I always held a head canon that the Doctor was actually giving a psychics lesson here, but because it was so complex and so far out of the understanding of the school kids, the TARDIS simply translates his speech to repeatedly saying "physics"
