Some of us will be able to choose if we want to die one days.
This was not a common idea in the year 2023, sadly.
The majority still thinks this idea is crazy.
Currently people think they would be lucky if they lived for a 100 years on this earth.
That is not looking far ahead though when it comes to innovation. 
It is just on thing that is going to happen.

Oh, and of course people are going to live on Mars and on other planets.
Also a lunatic idea in 2023.
Everything you can think of you can do.
