Answer:
What do people spend a lot of money on every year, but never want to use?
Cold head and feet; round as a ball; always turning around myself.
I go around in circles but always straight ahead never complain no matter where I am led. What am I?
Without a bridle or a saddle across a thing I ride a-straddle. And those I ride by help of me though almost blind are made to see.
I have two bodies joined together as one. When standing still I run and run.
If itβs information you seek, come and see me. If itβs pairs of letters you need, I have consecutively three. What am I?
