Lead is a very serious heavy metal that will mess up your brain and your body if you get it into your system. Lead lowers IQ, causes temper problems and depression, hearing loss, anemia, and so on. Once lead gets into a person's system, it can stay there for most of that person's life, often causing sporadic damage as it leeches out of bone and becomes reabsorbed. Lead is a very soft metal and therefore is not safe to handle with unprotected hands and you should not allow it to come into contact with things by rubbing so that it gets spread around. People usually handle lead glibly and don't realize that it's affecting them negatively, because it's a very incremental process. Beethoven's deafness was caused by lead poisoning. Don't shortchange yourself. Use disposable gloves, wash your hands, and be careful about having it rub against anything.
