When I look back, my hiking trail seems more like the interior of an intestine. The roots and trees form the intestine wall, which is full of sensory nerves.
An army of virus moves around freely, exploring every nook and cranny.
They stay inside, waiting for available chance; they never do a needle-poke, they tickle.
Inducing laughter is a fabulous thing. The army is sent deep inside your body. They will start tickling the moment you find me.
A friendly reminder: Please don't force too hard in the morning routine, you may pass these good virus into the sewerage.
