I was thinking of hot to make it possible so I thought of just cutting the vein or artery to which connects to the main brain...well I can't explain it but ye
I know I'm 2 months late to the party, but...

Have you considered the possibility that nothing is wrong with you? :)

Ideal sleeping times shift quite a bit throughout our lives. Plus, every person has their own ideal bedtime. Some of us are just naturally nocturnal. And if you're a teenager you might not actually get tired until 4 AM.

I can't say if it's by design, but this kind of thing would have been advantageous to humanity in ancient times, as it meant someone in the tribe was always awake and looking out for wolves. Nowadays, we've got a system that attempts to force everyone into the same sleeping schedule. It's disaster especially for teenagers.
