If this theory is true I guess it means she died at around 100, which is still honourable.
It would have been interesting if she had lived to 120 like a real supercentenarian, which means the fake age of 142. Then at least we would have been sure that something's off.
> she had lived to 120 like a real supercentenarian
The point is that no one ever lived to 120 in a provable way, so it's not something that could have happened to the daughter. Also in the swap hypothesis Yvonne made it to 99, not 100.
