Imagine you are watching the world and the world moves in slow motion (as in movies). Are you fast or slow ?
If the answer is slow:
World is moving slowly w.r.t. you. so you are not slower.
If the answer is fast:
You are watching and you know you can not be faster to watch !
If the answer is while watching you are neighther fast nor slow:
Is n't it amazing, we can see slow motion real time world by just watching ?
It is upto you whether you want to feel or understand!
