"It is not possible to step into the same river twice." 


When you step into a river, you change that river by being in it.


Neither you, nor the river, are ever the same again. And so it goes, moment by moment, with memory.


This phrase is a loose translation attributed to Heraclitus, a Greek philospher (c.535 – c.475 BCE)


We fundamentally change our body, and therefore memory, as we respond to our environments.
