I can't imagine why you would need a cloned body. With the level of technology needed to make that work, you should just be able to rejuvenate the one you already have. The body is already self-repairing, the problem is that the aging process makes this mechanism faulty. That can be fixed. If your cells can easily grow and multiply from a zygote into a mature adult, there's no reason you can't fix the flaws which prevent total rejuvenation. It might require nanites though. But that still sounds easier than a brain transplant and then manipulating the brain to learn like a 5yo again.

The later is surely science fiction, but brain transplants - which really, are just figuring out how to perfectly reconnect spinal tissue, which while incredibly hard is not something completely fictional since we have already done it in very reduced test cases (and we know that stem cells are likely going go give us an easy way eventually to just regrow the gaps in the spinal column) are not nearly as far out as nanites of the sophistication to modify organic cells are right now.
