This is our big mistake:
to think we look
forward to death.
Most of death
is already gone.
Whatever time
has passed
is owned by death.
— Seneca

Since you do not know
how many years you will live,
you might be closer
to your middle age
than you think.
However young you are,
you might have passed
your middle age,
with most of your life
already over.
