I die a tragic death in order to save everyone else without them even knowing.
Scenario: There are five people in critical condition who each need a different organ transplanted into their body in order to survive. I come in for a regular check up. The doctor tells me that if he kills me, he could use each one of my parts to save the five other people who are currently in the ICU. They will have long lives in the future after this surgery is performed. I say sure. I get cut up and save the five people without them knowing I needed to be sacrificed in the process.
