You can also see how some people have to descend tens of meters with cables and ropes to fetch water with buckets and tons of water; something they have to do on a daily basis.
Outside the cave, scientists are keeping an eye on the team. They want to find out how people and their bodies react to an ‘extreme lockdown’.
Christian Clot explains in his audio message that it is sometimes difficult to work together. There is no sunlight in the cave and there are no bells. No one again because of what time it is. “Sometimes I wake up and others just go to sleep. So you can’t make an appointment with someone and say, ‘we’ll see each other at breakfast’.”
