Gandhi

Mahatma Gandhi walked barefoot everywhere, to the point that the soles of his feet became quite thick and hard. He was also a spiritual person, and even when he was not on a hunger strike he did not eat much and thus he became quite thin and frail. Furthermore, due to his diet, he wound up with very bad breath. This explains why he became known as a "super calloused fragile mystic vexed with halitosis."
