Before nanotechnology:
Peoples life were tough
People will die easily
People will be afraid of when they will die
People have to survey to look for people that is injured
After nanotechnology appears:
Peoples life were better
People won't die easily
People will not be too afraid of when will they die
People just have to sit down to see whether were there any people that is injured.
Before nanotechnology was invented it is by walking.
After nanotechnology was invented it is by controlling machines.
