Are You a Morning Person?

[Riverman]

I'm definitely a night owl and recently got a wrong result from DNA.Land about it, like most if their results don't reflect my actual phenotype. I thought about a fundamental question differentiating morning from evening and night people and came up with a job-related one. If you have to work for a job either until 5 in the morning or from 5 a.m., what would you choose?

My biological clock seemed to be longer than 24 hours before age 40. My schedule always had a tendency to drift later and later.
After age 40 it's been then opposite: my biological clock seems to be less than 24 hours and my schedule has a tendency to drift earlier and earlier.
Anyone else like that?
Any published variants that might be related?
