Caves are rather uncomfortable but fascinating environments, you need be aware of obstacles, directions, yourself and your teammates, as well as be alert to dangers. All this is in just the dim light of a helmet torch. And that, of course, means moving in full control of your body. A simple injury to an ankle or a wrist could make the exit unreachable without help.
Astronauts need to be cared for. So for CAVES 2013 I decided to involve a medical doctor to support the extended expedition in addition to the external support of the Sardinian branch of the Italian Cave Rescue organization (CNSAS).
As with all team members, I needed someone who could be multifunctional. Giacomo is an expert speleologist, and has supported us as a medical doctor before, but he is also as an expert in caving and roping techniques. He monitors safety with a tremendous motivation and makes sure everybody is in swinging shape.
