What goes up but never comes down?

Your age.

I have a head and a tail but no body. What am I?

A coin.

The more you take, the more you leave behind. What am I?

Footsteps.

Everyone has it and no one can lose it. What is it?

A shadow.

What has hands but cannot clap?

A clock.

It gets bigger and bigger the more you take away from it. What am I?

A hole.
