California requires the following notice:

Warning to all members, after touching solder wire, PCB, wires and or components wash your hands. Blow your nose to be safe. Those that have finished reproducing or beyond "that age" may ignore 1/3rd of this warning.
I would like to see a study of "reproductive harm" comparing 63/37 Eutectic, 60/40 and 50/50s solder before I decide what to use.
