How would you enforce this law. To claim this the person you are trying to save is already in the hosptial and can be no help.
Yeah. Say a woman is hospitalized and all messed up, and her husband has to make the call (a call that might be 'she lives,' you know).
Wait a second! Some idiot comes in and points out that the loving hubby had sex with his secretary at the Christmas party 4 months ago! FOUL!
So does that qualify as adultery? Now he has no say in the matter? So who gets the say then? Parents? What if they aren't any. Siblings? Then who?
People should just get living wills - while not perfect, they do make the person's intent crystal clear.
It is possible that, for example, a married woman can be getting sex from that hunky UPS guy once a month every time he delivers one of those monthly baskets of fruit (that her hubby got her!), and still dearly love her husband and make a fair and wise call on his life.
Then again, maybe not.
Sheesh!
