Well neither did lead, in the olden days. Not in a weekend, that is.
Of course any fear such as it exists (and regardless of how ill-founded or well-founded it may be!) is not about weekend wipe-outs but rather slowly creeping seeping insidious very-long-term poisoning accumulating and unnoticable from day-to-day, until who knows "suddenly" at some point the entire population has at least half a dozen ailments of civilization, new-fangled "syndromes", mitochondrial or neurodegeneration, and depends on dozen of pills..
