[185] **Then indeed he dies even of old age** — means: when a person is old (jiṇṇa), aged, elderly, advanced in years, come to the final stage of life, with broken teeth, grey hair, the hair fallen out, bald-headed, wrinkled, the limbs blotched with age-spots, bent, crooked, leaning on a stick — then he passes away, dies, disappears, and dissolves through old age as well.
There is no release from death.
As for ripe fruits
there is danger from falling in the morning,
so for mortals once born
there is constant danger from death.
Just as clay vessels made by a potter
all have breakage as their end,
so is the life of mortals.
The young and the grown,
the foolish and the wise —
all go into the power of death,
all have death as their destination.
When they are overcome by death,
going from here to the other world,
no father can protect his son,
nor relatives their relatives.
See! While the relatives are looking on,
lamenting greatly,
each one of the mortals is led away
like an ox being led to slaughter.
Thus is the world afflicted
by death and by old age.
Then indeed he dies even of old age. Therefore the Blessed One said:
Short indeed is this life;
one dies short of even a hundred years,
and even if anyone lives beyond that,
then indeed he dies of old age.
