Hi JUC,
For this argument to fly I think you have to demonstrate two things;
1) That there are adults in comas who have the same level of mental/nervous activity as a foetus and;
2) That some of these same people wake up from their comas.
Unless you can demonstrate that (and I don't think you're going to able to), none of this makes any sense.
