I am a senior in High School, as well as a biotechnology student. I have done extensive research on telomeres and the possibility of removing the Hayflick Limit entirely. In a very close vain, I have done much searching through cybernetics and bionics. This leads me to a question I struggle with " Is it possible to bit-by-bit replace the human body with bionics, leaving only the brain". We have been able to create synthetic neurons and connect bionic limbs to where other limbs used to be. I also struggle with the indefinite problem with aging within the brain and if you could recreate that in the same way. If you have any input at all it would be much appreciated.
