Backs are a lot of fun!

Backs are a lot of fun!
They give piggy back rides,
and enable us to receive back massages.
Pats on the back from friends are a nice feeling when you're down or you did something well.

My back is my support.

My back is my support.
It is straighter that most,
with the help of a stainless steel bar.
I wonder if it's stronger?
I haven't used it to carry children,
but it holds a backpack just fine.
It's scarred, but the scars are rather cool.
My back is the highway to my head and to my butt.
