Spending $50,000 in order to receive the far-flung benefit of "living forever" sounds like just about the most conceited, biased thing a person can do. What makes YOUR interests so special? That amount of money can have the almost certain benefit of saving lives right now. Some ~25,000 children die each day from malnourishment and poverty related diseases.
I'm not suggesting, however, we need to live every waking second with the thought of Peter Singer's preference utilitarianism weighing on our mind. Setting aside tens of thousands of dollars for "scientific resurrection" falls into a different category.
