Your point is well taken, Chris, but a technicality here: lead didn't wipe out the Roman civilization. That was a popular story often told, but it's just not true. Lead pipes didn't contribute enough lead to do any real damage. Some bodies analyzed showed extremely high lead while others didn't. Further research indicates that the wealthy Romans had a drink made from boiling down wine in shallow lead vessels until it became a syrup. That was then added to wine to make a thick, sweet drink. It was, unfortunately, sometimes given to babies to help with colic. The point of all this is that the tiny amount of lead in a guard solder joint is not going to poison your dinner.
Modern epoxy works so well - esp. combined with pinning - that soldering has really dropped off in popularity.
