"What is the value of a life?" they would ask. I had a very simple answer -- how much life insurance do you have on yourself? That is what you think a life is worth.
If you have $500,000 in life insurance and I offered you $600,000 for your life, would you accept it? If life insurance determines the value of life and you were a rational actor, you would gladly give up your life for any amount of money that is greater than your policy.
