Answer:
What can you break even if you never touch it?
I help engines spin and pants stay up. What am I?
I have a hundred legs, but cannot stand. I have a long neck, but no head. I cannot see, and I'm neat and tidy, as can be. What am I?
I break away from my pack. I create holes in my victims. I can travel for miles and then disappear. I am part of a dying breed. What am I?
No matter how little or how much you use me, you change me every month.
