My phone goes into Do Not Disturb about an hour before bed, and I place it face down on the nightstand.
I read daily before bed to wind down.
I've considered revisiting psychedelics, but it's been a long time since college!
I exercise daily, mostly high intensity aerobic, pushups, pullups, situps, indoor rowing, or hiking.
The phone stuff is really getting out of control, and I'm not sure what the solution is for less disciplined people. Dating sucks, going out socially sucks, going to concerts sucks, all because of the pervasiveness of the modern phone.
