    Your body replaces all of your cells over the course of 7 to 10 years. So every 7 or so years, you are literally no longer the same person that you were. What’s the difference between that and expediting the process with a transporter?

      This is not true. 7 years is the average, but some cells are with you for life. Others a few months. When you die, you’ve likely only replaced about 40% of the cells in your heart, the rest have been with you since birth. Same for many regions of the brain.

      Not true. The neurons of your central nervous system for example become fully differentiated during embryonic development, and then lose the ability to mitotically divide, which means that they stay for life. All your brain is doing after that is making synaptic connections between neurons.
