Old dogs, old cars and old friendships all got that way because somebody kept taking care of them.

Nothing lasts by default. Anything old and still working was maintained by somebody who kept turning up with oil, attention, or a phone call, usually at moments when it was inconvenient. Age is not luck, it is the accumulated result of repeated upkeep.

Pick whatever has lasted longest in your life and do one piece of maintenance on it this week. Neglect is slow and nearly invisible right up until it is not.
