Never resting, never still. Moving silently from hill to hill.

My first four letters describe all living things.

I saw a man in white, he looked quite a sight.

I speak without a mouth and hear without ears. I have no body, but I come alive with the wind.

What 4-letter word can be written forward, backward or upside down, and can still be read from left to right?

Re-arrange the letters, O O U S W T D N E J R, to spell just one word.

I am something people love or hate. I change people’s appearances and thoughts.

Only one color, but not one size, Stuck at the bottom, yet easily flies.

Who makes it, has no need of it.
Who buys it, has no use for it.
