Turning over

"..., the entirety of the functional

components of your whole CNS have

been broken down and resynthesized over

a 2-month time span. This should scare you.

Your apparent stability as an individual is a

perceptual illusion."

.......

"Development puts everything in its right place, but maintaining that

anatomical structure is an active process,

and the component molecules are turning

over with surprising rapidity."

J.David Sweatt
