My point is exactly proven by your post. If that were the whole story then why would however many courts this has been thru not overturn the ruling of the lower court? It doesn't make sense.
Let's just say for a moment that this lady is being kept alive artificially, and has been in such a state for a long period of time. Long enough that it is clear that her body lacks all ability to recover, however she could be kept alive in her current state for some time. Beyond that, let's just say that it is truly her wish to not be kept alive in this a state, where you are confined to a hospital bed and kept alive by a machine and there is essentially no hope of recovery (for the record, that would be my wish too). Given these assumptions, it seems reasonable that this guy would want to move on with his life.
Really, this whole situation makes me want to sit down and write up a will. Unfortunatly I need to get to work at a more decent hour tomorrow, and so I should go to sleep instead.
