A metaphysics to ponder between innings.
As a person grows older, she approaches or reaches her "fair share" of life - her fair innings.
In baseball, it is an inning victory for a team to get three opponent hitters out without scoring.
Indeed, for any given baseball game it is possible that the game, or even the first inning, last for an entire year.
There is, however, another way of interpreting the notion of fair innings.
When they reach 70, they had their fair innings, and the remaining years are "bonus time".
But if a person has had her fair innings, saving her has strictly smaller value (perhaps none at all).
The older person is saved for certain, although she already had her fair innings.
