I would imagine they have all lost some weight. One really good thing is they have set routines for work, sleep, personal time, etc. There's a neat sort of grid with pictures of each team on THIS PAGE. The oldest one, who is 63, has been working down in the mines since he was 12 and had been thinking of retiring. 53 years of working down in there! Amazing fellows.

May they all come to the surface, safe and well. What a wonder this has been and will be..such an incredible feat and example of what good folks can do for a common cause.
