Imagine two astronauts go to the moon, and while they're there, there's an accident and their ship can't take them back to Earth. They have only enough oxygen for two days. There is no hope of someone coming from Earth to rescue them. They have only two days to live.
If you were to ask them at that moment, "What is your deepest wish?" they would answer "To be back home walking on our beautiful planet Earth." They wouldn't think of being the head of a large corporation, a famous celebrity, or the president of the United States. They wouldn't want anything but to be back here - walking on Earth, enjoying every step, listening to the sounds of nature, or holding the hand of their beloved while contemplating the moon at night.
