Let’s say that the entire second half of your life is a dream but you find out that your real body has been in a coma for only one day but you now can wake up. If you do wake up, you’ll wake up exactly at half the age you currently are. Anyone you meet during the second half of your life is gone now and anyone you lost is alive again. This includes all technology or companies created in the 2nd half of your life. Do you decide to wake up and live in the real world or stay in the dream world until you die. Assume when you die in the dream world, your real body dies in the real world. You can use any knowledge you gained during the 2nd half of your life but the events are not guaranteed to play out the same as in the dream and you may or may not re meet some of these people or variants in the real world.
