on the radio, they said yawns were contagious
athletes, performers all yawn just before.
it raises the awareness and the heart rate.

they said pack animals -lions, dogs, your nieces or nephews
they trust you if you do... and then, they do it back.
it prepares us for the hunt.

I tried with someone at work, but
they did  not kindly yawn back;
will I stop believing in the radio,
or that I really don't like co-workers.
