I was thinking about how numerous immortalists see brain transplants to cloned bodies as a possible approach to continuing their being

This brings up the source of variation between clonal groups or monozygotic twins. Many MZ twins are tremendously similar, others vary noticeably. a person seeking to have a fully identical body, with fully identical microphysiology as well as various cytokine amounts or body side neurotransmitters would likely prefer theleast varying clonal body.

Like we will simply say that vitamin D has mild beneficial effect on a fetus. Thus two different groups of monozygotic twins could vary as a result of the parent getting either more sunshine, or, having the "tanless" gene that causes people to make the same amount of vitamin D even with widely varying amounts of sun. It is possible there are personality genes that cause similarity or divergence among MZ twins as well resulting from more widely varying perception at the CNS.

Thus we see there are genes that could cause some groups of clones or MZ twins to variable at their physiological identicalness. Thus a person creating clonal bodies to be am immortalist might want to create a list of the variability multipliers they had as well as those of their cloned bodies.

which brings up the slightly different idea that a nonidentical near clone, that had controllable variability, could be a better body replacement than an actual clone.

My honest opinion is brain transplants are needles to begin with.
The technological level needed to transplant an actual brain without damaging it and meld it's nervous system with the donor body efficiently, would make the whole point of doing the transplant moot.

If we can preserve a body so perfectly that the brain won't be destroyed AND have the capabilities to make neurons (which would imply we can do the same with other tissues) to grow at will in vivo I don't see why we couldn't just suspend the ill body in animation and fix whatever is wrong with it.

The only case I can see this procedure being done is for people who got their heads cryopreserved.

the problem is that the axon fibers which have to meet with the transplanted brain's fibers
we speak about millions if not billions of axons and there is no gaurantee that the fibers are in the exact location even in a clone.
i think a more viable option would be to regrow the body from stem cells around the brain.
maybe some growth accelerating, or you can be a genius baby with a giant head(brain)

From my clinical practice I can absolutely confirm, that the problem with the axons will be extremely hard to be solved. If one simple stupid peripheral nerve is cut, its repairing is being done hard from the clinicist, its recovery lasts months (some times years), and its recovery is uncertain, no matter what methods You are going to apply. Suturing all the nerves to the new body will definately be extremely hard, and their full recovery is questionable. Moreover, there are nerves, that if cut may lead to death. Waiting for these nerves to recover for months or years will be something extremely hard and maybe impossible and should involve managing the patient for months and years on a life support systems. Moreover what will be done if these nerves actually do not recover?

I have to disagree, at least to the ends of being enlightened.

I would want to have a new body made for my head to accomplish or re-mediate the following:
*when a person is obese, there body grows in ways that can't be fixed by diet and excercise
*poor nutrition/health growing up can also leave an imprint on the body's form
*fixing the accumulation of scars and other damage may require more resources and effort than growing a new body

What do you guys think?
