CONTAGIOUS

Sickness is contagious.
Laughter is contagious.
Divisiveness is contagious.
Inclusiveness is contagious.
Love is contagious.
Hate is contagious.
Smiles are contagious.
Kindness is contagious.
Life is not a Wheel of Fortune,
you get to choose
what you will be contagious about.

Also considered "smiling is contagious", but I think the "are" is good to break up the monotony.
