John has spent his whole life mining rocks. He has been doing this job for more than thirty years. It is a quite respectable time span, and Johns dedication and love for what is he doing must be real. When you meet him at local pub, he is always telling people many interesting stories. "One day, I caught pair of boots... I was like, what the hell?" Or... "It was Monday afternoon, and I spotted something shiny, was it a piece od diamond? No, it was just pure glass from a bottle of beer... Damn...!" Who knows, what is he going to mine tomorrow! Have fun.
