I have a heartbeat made of traffic, a voice made up of countless tongues. Though built of stone, glass, and steel, I seem alive to everyone.

Leave bread too long and I may grow, yet molten metal may use me so. In one form living, in one form not, yet both share a name, believe it or not.

I wear a coat of green armor but have no wars to fight.I drink deeply when it rains but can survive months without a sip.Touch me and I will bite, yet inside I hold a hidden well.

I have buttons down my front, but I am no toy. I may be short or long, stiff or soft. I can be plain or patterned, formal or casual. What am I?

I vibrantly fluff up your bags and gifts, I anchor your muscles and repair rifts, I float through the air when I catch a breeze, And stop the explosion of your sneeze.
