Becoming A Gold Miner

I am a young boy name Marcus and I am a Gold Miner. 1 thing I am scared about working at the Gold Mine is putting Mercury on my hand, I know it attracts gold but I am scared every-time I put it on my hand. The reason why I get scared of putting it on my hand is because I can get a disease like Mental Retardation. Working at the Gold Mine is not fun unless I get to work with my friends, but most of the time I am not happy. If I could change anything it would be for me not to work until I am an adult. It would be for every under aged kid to work when there an adult.
