Can anyone in the house tell me what on earth he or she can die for?
Hm... so if you were at home relaxing with your wife, I could burst in, point a pistol at you, and yell out "Freeze! I want you to cut your wife up into small pieces, cook the pieces, add maggi, onion and salt, season with curry and thyme and then eat her! Co-operate, and I promise that I won't shoot you!" Would you 'co-operate', then?
I'm not sure whether you mean "what would i put my life on the line for?" or "What would i out right die for?"
So I'll answer both.
I'd put my life on the line to protect my integrity
I would never deliberately die that's called suicide.
If i ever died pushing someone i cared about from a speeding car (or something to that nature), my death would be purely accidental.
