What do you think is better for a person's health?

Either one.. as long as you get enough sleep

That's dependent on the individual.

Wake up early, exercise in the morning. You'll tend to have more energy through the middle of the day and will sleep well. Then just repeat the pattern daily

It all depends on the person. Some can do both and be in perfect health mentally and physically. Some need one or the other.

A working CO detector, and living deep in the woods away from air pollution

Waking up early because people are meant to be awake in the day time

I really wouldn't know, I've never tried waking up early lol

well i've always felt better waking up early.

Equanimity in thoughts and action.

Don't do it

hard to say.
