I'm over 40, I have decades of experience, at this point I know for a fact that I am not productive until 9 or even 10 am, and there's no amount of changing sleep patterns or getting more sleep that affects it, it's just my hardwired, unchangeable natural rhythm. If I had my way, I would change the day to 9-6, but my vote doesn't count apparently.
