Two bold talks released in one short week. Both given at TED 2007.
  1. Bill Stone - maverick cave explorer and diver talks about his explorations and ambitious Shackleton exploration project.
  2. Hans Rosling - Professor of Global Health from Sweden. Statistics can be compelling.
Both inspiring beyond what words can summarise. Therefore no summary here but only their concluding remarks.

Bill Stone's message -
Men Wanted:
For Hazardous Journey,
Small Wages, Bitter Cold,
Long Months of Complete Darkness,
Constant Danger,
Safe Return Doubtful,
Honour and Recognition
In Case of Success.
-- Sir Ernest Shackleton, 1954

Hans Rosling's own message -
Seemingly impossible is possible. We can have a good world.

Both Remarkable!
