Wake me up when I am in deep slumber, shake my shoulders and shout - 'Who are your heroes?' No epithets shall pour forth from my mouth, but I will mumble - 'Eric Shipton, Ernest Hemingway and George Schaller'. Maybe later, clearly woken up, I might light a cigarette and ponder upon your query and make out a longer list; but the above three will top it.
What makes a person your hero? Googling the word and cutting through Hero Cycles and Anil Kapoor's movie and such riffraff, I find these definitions:
b.in the Homeric period) a warrior-chieftain of special strength, courage, or ability.
Upon that mountain: Eric Shipton.
