That's how it seems to me, too. I seem to stay that way all day long, sort of relaxed, confident, non-paranoid, outgoing, energetic, pensive, everything good combined together even if they seem like opposite feelings!
On the flip side, I met a guy who said cycling made him puke.

I found out later that's a common sign of being totally unfit, cured only with exercise (beginning gently).
