Many things am I, the foundation of many parts of life, in and outside the body, I make buildings steady, swords strong and when I decay red is all that's left.

It can go up and down, Twist and turn, Solve your problems, Or carry the tone

In fields of green, I stand so bright, A golden sun in morning's light. With wishes blown, I take to flight, A gentle puff, I'm gone from sight.

I can speak in every voice, sing every song, even give every speech. A great connector of man, though for you to hear my words, I must sit on your head. What am I?

Cleaned and polished in your drawer I sit Getting me dirty is a job that fits Big or small your face warps wide If you focus hard you can bend me with your mind
