How can I remember what I was doing ten years ago when all of the atoms in my brain are being replaced every couple of weeks?

All of these atoms inside of my head are vibrating and colliding with each other. Their movement allows the intricate web of electrical impulses scatter and come together in new designs never thought of before.

These are some more thoughts that have been inspired by Richard P. Feynman in his essay The Value of Science which like most of the other stuff he wrote I enjoyed immensely.

"So what is this mind of ours: what are these atoms with consciousness? Last week's potatoes! ... To note that the thing I call my individuality is only a pattern or dance ... the atoms come into my brain, dance a dance, and then go out."
