what life means?

A plane was about to crash in Tacloban; there were 5 passengers on board, but only 4 parachutes. The first passenger said, "I am President Aquino, the chosen one. The Philippines needs me, I can't afford to die." So he took the first parachute and left the plane. The second passenger, Mar Roxas, said, "I am the next president of the Philippines, so Filipinos don't want me to die." He took the second parachute and jumped out of the plane. The third passenger, Dinky Soliman, said, "I'm the Secretary of DSWD, a lot of people depend on me." So she grabbed the parachute next to her and jumped. The fourth passenger, Mayor Duterte, said to the fifth passenger, a 10-year-old Boy, "I have lived a full life, and served my country the best I could. I will sacrifice my life and let you have the last parachute." The Boy said, "That's okay, Mayor. There's a parachute left for you. President Aquino grabbed my SCHOOL BAG."
