Though most human cells are constantly being replaced, we keep most of our brain cells (and some others) throughout life. While a specific brain cell continues to exist, are the individual atoms in that cell gradually being replaced? Are individual atoms replaced in cellular DNA? Quantum physics tells us that atoms are popping into and out of existence all the time.

Atoms are constantly replaced in everything.
