Both my house and the Liberty ships were built at the same time during the
same material shortages.  I'll bet the Liberty shipyards got the better
timber.  But my point was that engineers design things mostly to operate
within expected environments.  What might be sufficient for most uses:

1) Everything except rough seas in extreme artic cold for the ships, and

2) Everything but an extreme snow load for my house

Now I'm pretty sure my basement's not filled with 40' waves at 40 below zero
(although it does smell a little like cod after a ten-year flood) but the
analogy still holds, at least IMHO.

Overengineering is why I *used* to like Compaq PC's so much.  They used
connectors rated for 10's of thousands of insertions instead of just
thousands, at least in the early PCs, and that gave them an "edge" in
reliability that other machines of the era could not match.  There was a
price premium, but it was worth it.
