Yeah, that's probably true, but he was suggesting putting the old (i.e. not a cloned) brain into the new body. I'm not a biologist so I don't know what causes the aging process to begin (or more precisely, I know that it somehow involves a decrease in mitochondrial activity, but I don't know what triggers that), but if it's just a part of cells aging and replicating too many times, then swapping the brain into another body should undo that aging.
Though there is the problem of brain cell death. Could that be addressed by the introduction of some stem cells onto the old brain? Would they be able to generate new brain tissue to replace the dying cells?
ah yes, my bad. i totally misread lol- tired eyes

. thought he said replace the old brain...
with that though, there are still some troubles
1) wiring all the connections... i mean severed ties in those that are generally not repaired. so if they cannot connect nerves in paralyzed people, how are they going to fix nerve endings in an old brain to a new body.
2) you would have to have a new body just waiting for the brain to come and would have to be about 3 minutes away from that new body before the brain cells start to die due to lack of oxygen.
3) expense. it would be quite expensive to keep a new body just waiting for you and keep it at required needs - ie temp., pH, etc
