It was a thought provoking article. I remember going down a zinc mine in Bolivia, where men work very hard in terrible conditions for a wage that comparitively is one of the better jobs to have in the area, but in reality (even for Bolivia) is a pitance. As a result it gives them an average life expectancy of something like 55. I thought at the time that I would never moan about my life or work conditions again - but sometimes you get wrapped up in your life and your own little issues and forget about the bigger picture.
