Why would you go to the coldest place on Earth? A place mostly devoid of life, where there are rarely more than a few thousand other humans spread out across a landmass twice the size of Australia. A place whose sublime beauty is matched by its capacity to kill you, very fast.
We are talking about Antarctica. A continent which belongs to no nation has no government and is run according to an international treaty signed nearly 60 years ago.
Shabnam Grewal went there many years ago and knows the joy of being surrounded by ice blue glaciers and the hardships of working in a freezing climate. She talks to others who were drawn there too, by the beauty of the place or in search of knowledge or to test themselves and understand who they really are.
