Are the cells in your body right now the same exact cells you was born with true or false

False.

Explanation:

Your cells are in a constant state of dieing and being replaced by new cells. As a result, very few of the cells in your body now are the exact same cells that you had 20 years ago. Your cells are constantly dying, but they're being replaced with new, fresh cells. ... The average age of a cell is 7 years… but that doesn't mean that every cell is replaced in 7 years. Some cells, in fact, never get replaced at all, remaining with us from birth until death.
