What s this for?

Дмитрий Бек-Лемешев
You’ve got two ears to hear with;
A nose, a mouth, lungs to breathe;
Your hands with fingers pick up things;
Your head imagines, guesses, thinks.

You've got two legs – they are to walk.
You've got a tongue with which you talk.
Two eyes for things you should look after.
You’ve got a smile, a friend of laughter.
