Molecular Rebirth: The Changing You

Every 7 to 10 years, nearly every atom in your body is replaced. That means the “you”

from a decade ago is made of completely different physical matter than the “you” reading this

now. This happens through natural processes like cell division, metabolism,

and atomic turnover. Scientists estimate you replace about 98% of your atoms within a decade.

Your skin, bones, blood, even parts of your brain,

rebuilt, atom by atom. You’re not the same person on a molecular level,

yet your memories and identity persist. In a very real way, you are constantly dying and being

reborn without ever noticing.
