Mahatma Gandhi, of course, was very spiritual and he gave up most physical possessions and generally went around barefoot. This caused his feet to become heavily callused.

He didn't eat much so he was quite thin and fragile - and what food he did eat often consisted of oddly-spiced native dishes, so he always had bad breath.

All this of course made him a super-callused fragile mystic hexed by halitosis.
