Moisture is a big issue for standard lead-tin solder and over time it
can degrade a typical solder joint to the point of failure, although I'm
sure it also depends upon other chemical influences. Whether that would
happen in any of our remaining lifetimes is a point of conjecture.
There is a reason, however, that lead-tin solder does not meet code for
soldering copper water plumbing.
