Serotonin
Stepping out into the sun
(To capture and convert UVs),
The navigator leads the run
And takes the charge of "where-to-be".
Endorphins
Breathing hard, all discord numb!
A high like never felt before
Feels so much like the liquid hum
Of sharing two, or three, (or four?)
Oxytocin
Splitting sides, we barely gasp,
Dreams afire burst forth and rush,
Time and praise are gifts we clasp,
We shudder-skip when fingers brush.
Dopamine
Rewarding sights come to the tough
And forming memories is my art.
Just sharing heights is sweet enough,
But anticipation rules my heart.
There are four chemical regulators for happiness. Some activities happen to trip them all off at once.
