I make wallets cry and bags feel proud. I start with ‘just one thing’ and end with receipts longer than a saint’s patience. I’m not exercise, but I can make you tired. What am I?

I speak loudest when nothing is said I fall the moment a whisper is born. Kings fear me in crowded halls I have weight yet no form I can soothe or suffocate I end wars answer questions without a sound Break me once and I am gone

I wear black and white but I’m not alive. Cars must pause so people arrive. I look like a zebra frozen in place. What am I that helps you cross alive?

Worn in cars, planes, and trains, but in the future spaceships did them away.

With brass, steel and nickel I help to unseal all manner of possibilities, I Bow then my blade bites, you turn me and then things open.
