I don't understand the meaning of this response. You seem to be suggesting that all memories are in the limbs. I don't think that's what was being suggested here.
Trying to stay within what I think you are saying, don't forget that if you amputate some insect's legs, they will keep flicking around for a while, even though there is no connection to the brain. Surely the insect doesn't suddenly forget how to move it's now missing leg. But the leg does seem to have its own capacity to remember how to jump or whatever even without the brain. Until it runs out of energy, of course.
You can cite your body. Before you get offended, really, just examine it as a system, and try to explain how can you have a conscious experience without any sensory input.
Even with a lame comparison to computers, the machines also need a lot of stuff to put a CPU to work.
Also, if the mind is fully integrated with the body, how you explain seemingly inconsistent states that seems to work just fine. Eg., people with ALS or quadriplegic or severely injured or mutilated. If the mind can perfectly works without a perfectly abled body, where's this mind body connection? Also, where's such connection in a comatose brain with a completely funcional body? Maybe I misunderstood what this mind body connection is supposed to be.
Sensory deprivation is interesting, but you already have a conscious experience when you enter the tank. It even reinforces that your mind is tied to your body.
I think the second sentence is opinion, not something that could be objectively tested. Last sentence is mostly true. Sick people are much less happy than when they are healthy.

In short, the biomolecular machinery that neurons use to think is present in all cells.
