Old man's tale

An old man walked barefoot everywhere, to the point
that his feet became quite thick and hard.
He also was quite a spiritual person. Even when he on a hunger
strike, he did not eat much and became quite thin and frail.
Furthermore, due to his diet of raw grains, he ended up with very
bad breath.
Therefore: he came to be known as a: "Super calloused fragile
mystic plagued with halitosis."
