Human beings are constantly growing and shedding cells. This means that very few of the cells that any person has as an adult were the cells that they had as an infant. Over the years, as we’ve learned more about cell growth and death, we’ve learned that our bodies aren’t fixed objects that simply change shape over time. Bodies are ever-shifting collections of physical stuff. To co-opt a phrase from Heraclitus, no one occupies the same body twice.
