Endorphines, contagious?

Sometimes, like tonight, I wonder if endorphin highs are contagious. Tonight I led an amazing training. The intensity was high, the girls were focussed and improving by the minute and by the end ready to never get up again and drenched in sweat. Everything just worked. The chemistry clicked for everyone.

So why did I leave on a high? I didn't physically do anything more than stand in the middle, talk, sometimes scream and take on derby stance a few times. Well, ok, I jammed on shoes a few times, but not in an actual jam, just in a drill to help out. Just some pushing into a wall of strong women. Didn't even sweat. Well.. didn't get wet of my own sweat at least.

I wonder what brain substance I'm high on.. <3<3<3
