At some point in the life of a product, something goes wrong, can't be fixed easily or economically, and we begin to lose confidence, worry about the expense of repairs, worry about encountering problems when it is really inconvenient, such on the high seas, on a deserted road, when there is fragile cargo still to be delivered.
We worry and we decide how to deal with the worry, either by replacing the boat or car with a newer model, or by hiring a good mechanic/handy-man to repair or replace parts that will give us back our peace of mind.
Not everything can be replaced, repaired or discarded.
Some things are too precious to fuss with or to discard: an old watch our Dad left us, the old silver urn Mother gave us, the mink coat, too out of style.
Don't you ever worry that we too may be too old to be repaired, too out of style to be relevant, needing too much to be maintained and treasured?
