Say you would be in a coma for 20 years after an accident.
Say they would go through 20 years of you being in a coma, then you wake up...
What would you think? What would you do? In the aspect of mind you are blown away, technology has advanced 20 years, if you have kids they may have moved out, started lives already, or something else might have happened to them....
In the aspect of body....you would have barely any muscle at all. (I think) you would barely be able to lift your own arms or even walk....
You would have to recover...
Say you would be in coma from 1992 to this year 2012.
I don't even know what I would do. First I would try to regain basic muscle strenght. It would take a while, but I will succeed..
Then I would just walk the streets... just explore...wander... see what my friends have been up to and more...
Of course I would be depressed that I would have missed 20 years of my life.
