Working on the Panama Canal has been strenuous on everyone. Working long long hours, not much break going time and days without eating or taking a break. That is a tuff task to ask of a human being. Noone was physically prepared for this. Being away from family devoting all your time to help and build something useful to everyone. Knowing people were dying and not survivng due to the conditions while building the Panama Canal. Tuff task for anyone to deal with idk how some people may it through but they are very strong and capable human beings.
