People are using prosthetic limbs today for their health.
I read about prosthetic limbs and how it improved people's life.  Prosthetic limbs
will improve how people use it by moving it in ways we move our limbs now.
Also prosthetic limbs are better than our limbs because they work in ways that
regular limbs don't.  The prosthetic limbs is safe for people because they help them
move their limbs in safe hazards.  People are already using prosthetic limbs today
so they can move their limbs too.
