Bad choice:

When Marine Lance Cpl. David Battle learned he'd either have to sacrifice his ring finger or the wedding band he wore, he told doctors at a field hospital in Iraq to cut off the finger.
. . .
Doctors were preparing to cut off Battle's ring to save as much of his finger as they could.

"But that would mean destroying my wedding ring," he said. "My wife is the strongest woman I know. She's basically running two people's lives since I've been gone."

With his approval, doctors severed his finger, but in the chaos that followed, they lost his ring.

I'm not married, so perhaps I'm not the best judge of this, but isn't replacing a wedding ring a lot easier than replacing a finger? Even when you factor in sentimental value?
