Jason Wright is the primary example of what go wrong with a solitary human living in equestria.

depressed, malnourished, shunned, you name it, it's happened to him. three years after he voluntarily came to equestria, his life is a good description of hell. after contemplating the end for a while, he started to go towards sweet apple acres. halfway there, he collapsed, and when he woke up, a stick, a cloak, and a helmet made of a reindeer skull laid in front of him.
