Hard, like Kung-Fu

Polar explorer Ernest Shackleton wrote the book on the loneliness of leadership. Even the harrowing ordeal of being shipwrecked on a block of ice for 2 years wasn't enough to alter his life's habit of only dining with the men on religious holidays.

In a marathon of endurance and stoicism Shackleon led one of the great round trip rescue bids of all time - saving all his crew and returning them to Europe in time for most to die for King & Country in the great war .
