Golem, I checked WebMD for you and it turns out that jobs where you are up on your feet a lot can cause a lot of problems with your legs. It could be gout that is exacerbated by the fish oil in the Guinness that you serve, or it could just be age. Have you considered changing careers? Maybe you could go back to school or try to work in the field in which you got your vocational degree. Just a few thoughts for you buddy. Love, Will
