Can you calculate the relative difficulty between to two sports? (i.e. Tennis vs wrestling, basketball vs boxing, etc.)

Conventional wisdom is that anything dealing with calculating the mechanics of a balls is more difficult than the human body. But I'm not so sure that's the case.

The question about climate change isn't the the change it self but rather if the Earth will reverse itself. How do you know the Earth will not reverse the course? Or how do you know we can actually materially stop the change?

What does it feel like to take a punch? Have you ever felt a punch so hard that you wanted to quit?

Do you still have relations?

It says "ask anything"? ;)
