Why do you wear disposable gloves when handling valves and also want to wash your hands after working with valves?
Lead deposits gets on your skin because you don't wear gloves. Then you have a samich for lunch and the lead makes its way into your stomach. Your liver and kidneys try to filter it out of your bloodstream; but, eventually can no longer protect your body from lead poisoning. You gain weight because lead is heavy. The lead heads to your brain and you start to forget everything like the Romans did. The hords of the Germanic Tribes take over the Roman Empire and you find yourself in a nursing home wondering where you are at. Before you know it, the Nurse feeds you a diet of oatmeal for the rest of your life....Wear your gloves and save the world; put the oatmeal farmer out of business which then causes an economic collapse of the Irish Economy. Now, the whole world has no potatoes because the Irish ran out of money from selling oatmeal and cannot fuel the tractors used to harvest potatoes...it's the world potato famine all over again....we just can't win! Still, wear gloves when handling valves.
