the only difference between you now and when your mom and dad made you is time and the number of cells.
Kinda but did you also know that those cells die constantly and are replaced constantly so that in 1 years time your body basically recreates and replaces every single cell in your body [not the brain though iirc]. Furthermore, your heart and other vital organs are on a much faster cycle, the heart is 21 days iirc.
