Answer:
I tremble at each breath of air and yet can heaviest burdens bear.
Iโm where yesterday follows today. And tomorrowโs in the middle. What am I?
In wealth I abound; in water I stand; as a fencer I'm valued all over the land; at Venice I'm famous; by farmers I'm prized; respected by law yet huntsmen despised; consternation and ruin ensue when I break; And the beasts of the forest advantage won't take.
I can be any color you can imagine. You see me in everyday life. Look around, you can probably see some of me right now. What am I?
What has legs but doesn't walk?
What flies without wings?
