Twenty French volunteers - ten women and ten men volunteers - returned at the beginning of April from their scientific expedition Deep Climate to Lapland. Europe 1 met them at the Brain Institute (ICM) of the Pitié-Salpêtrière Hospital.

The idea is to study how ordinary people adapt to extreme conditions. Next step in this climatic and human adventure is the burning desert of the Middle East. For confidential support call the Samaritans in the UK on 08457 90 90 90, visit a local Samaritans branch or click here for details.
