As an old plumber, we poured thousands of pounds of lead making caulk joints, used miles of lead wire solder, sanded no telling how many pieces of copper pipe. It’s s wonder I’m alive.
Sanding copper (Steamfitter) is exactly how I lost my liver.
Had transplant in 2006. 2 years in bed 24/7 with diarrhea 8 to 13 times
a day for 5 years wasn't’ like a a walk in the park.
