The proof that it's intentional is that Yamanaka factors work. They reset any cell, no matter the age or the specialization, to a perfectly young stem cell. Another proof is that heterochronic parabiosis works. Transplanting an old organ into a young body rejuvenates the organ as well. High concentrations of exosomes taken from young blood also have a rejuvenating effect.
