What does Heraclitus' fragment 88 mean? What does it say about existence?

Question

Fragment 88: And as the same things there exists in us living and dead and the waking and the sleeping and young and old; for these things having changed round are those having changed round are these.

Answer 1

My copy says:

"And it is the same thing in us that is quick and dead, awake and asleep, young and old ; the former are shifted and become the latter, and the latter in turn are shifted and become the former."

Basically things are in cycles.
