You may always chase me but you are always about 3 miles away. What am I?

From house to house I go, sometimes narrow, sometimes wide. And whether there's rain or snow I always stay outside. What am I?

I am two-faced, but bear one head. Men spill their blood for me. I have no legs but travel widely. I make kings immortal. I am potent when shared; Yet lust for my power keeps me locked away. What am I?

I can sizzle like bacon, I am made with an egg, I have plenty of backbone, but lack a good leg. I peel layers like onions, but still remain whole. I can be long like a flagpole, yet fit in a hole. What am I?

Not born, but from a Mother's body drawn, I hang until half of me is gone. I sleep in a cave until I grow old, then valued for my hardened gold. What am I?

Half of the population uses me, and you lose me all the time. I'm small and yellow, black, brown or silver. You use me to hold things up. What am I?

Ten men's strength, ten men's length, Ten men can't break it, yet a young boy walks off with it What am I?

I build up castles. I tear down mountains. I make some men blind, I help others to see. What am I?

I only have one entrance, but you can come out with three exits. What am I?

I have a mouth on my head and eat everything. What am I?

I'm lighter than air but a million men can't lift me. What am I?

If you eat me, my sender will eat you. What am I?

I am used to bat with, yet I never get a hit. I am near a ball, yet it is never thrown. What am I?

I am the ruler of shovels, I have a double, I am as thin as a knife, I have a wife. What am I?

I have a tongue, but cannot speak. I have a bed but cannot sleep. I have four legs but cannot walk. Yet I move as you do. What am I?

I know a thousand faces, and count the tailed heads, feasting bright upon the eyes, of many who have died. Wielding well a mighty power, who hath but humble stature. Masses fall upon their knees, to scarce behold my only side. What am I?

Many have heard me, but nobody has seen me, and I will not speak back until spoken to. What am I?

I fly, yet I have no wings. I cry, yet I have no eyes. Darkness follows me; lower light I never see. What am I?

If a man carried my burden, he would break his back. I am not rich, but I leave silver in my track. What am I?

You will always find me in the past. I can be created in the present, But the future can never taint me. What am I?
