Ushuaia: No place for old people

Down here, you can almost feel the edge of the earth pulling you forward.From Buenos Aires, you fly south over water first, for hours. Then you approach Ushuaia low over snow-streaked valleys, where ice smooths the cavities of sunless slopes far into December’s summer.A wedge of dwellings and sharp-edged warehouses, Ushuaia turns its back to the unimaginable wilderness of the Andes.
