For most of history, doctors had no way to stop pain. 

During surgery, patients felt every cut and stitch until they inevitably passed out. All a surgeon could do to minimize pain was work faster. 

That all changed when the first surgery was performed using ether as anaesthetic. 

Now surgeons faced a new dilemma. If a patient can't feel pain, when do you stop? 

Anything can be a race against the clock if you let it. 

Waiting for a promotion, having a child, eating the last yogurt in your refrigerator. 

Sometimes, you really are running out of time.

 Most of the time, it's all in your head. 

And when you let go of all that fear, the possibilities are infinite.
