I am a king who's good at measuring stuff.
I no longer have eyes, but once I did see. Once I had thoughts, but now Iām white and empty. What am I?
When it comes to me you go on red and stop on green.
When you stop and look you can always see me. If you try to touch you cannot feel me. I cannot move but as you near me I will move away from you.
Almost everyone needs it, asks for it, gives it. But almost nobody takes it.
