Performing a job like this is not easy, it is one of the hardest jobs in the world and what is sad these people are less paid for the job they are doing than for any other job in the world. it is not easy and what is worst the dust they are inhaling is very dangerous for their health. What is interesting this is job which all around the world is being performed like this and it is always done by the poorest people, which have no other way to make their living. Hard job, hard life, hard working hours and still those people are the ones with the smile one their faces. It is said that the big problems are quiet and the small ones qre the loudest ones. Can their working standard be improved somehow? Can these people get some technical help?
