Hypothetical questions by their nature can only offer possibilities and the possibilities can be endless. Zigner's brain implant theory becomes as legitimate an answer to Mark's hypothetical question as any other that is offered, given no facts to rule it out,Elsewhere the OP has indicated that this is, in fact, due to a real situation and not hypothetical at all. But for some reason he appears to find it difficult to understand that there are shades of grey and exceptions and when we attempt to answer questions with no context, we may give him incorrect information.
Ah, well. Mark found what was offered helpful. That's nice. And it was especially nice that he returned to the forum to express his thanks.
