In not so far off future, theres a virtual reality playset connecting to thousands (millions) of people enabling to smell, feel, taste, see a false reality. In this world, you design your human.... or elf or robot or ogre or mermaid.
Now, assuming your old and such you have more freedom physically in this world. No disabilities, no illness, dont gain a pound.
Would you live the rest of your days in this world, or not? This being close enough to reality that you cant tell it apart.... unlike virtual worlds on a monitor... you exist in this world.
