- You'd better be fit. The miners' waists cannot measure over 35" to fit through the rescue tunnel they are drilling. Survival is very physically taxing. You better be in shape before a crisis starts.
- You've got to keep your head in the game. The miners didn't give up hope during those 17 days when rescue was slow in coming. Now they have been found but it may be Christmas before they can get out. Can you even imagine? You've got to be both physically and mentally tough to survive that. It will be interesting to see how this plays out over the next few months.
