You know what that is. It's the sound of a heart, beating faster and faster.

It sends chills at my spine just thinking that it's actually the sound of a man's heart

who's leaning over the edge of an 87-story building. Oh my, he's looking down. He can barely see the cars below him. Scared of heights and trying to catch his breath. He realizes there's nothing to stop him from falling. He's not strapped to the building. There's nothing on the ground to soften his landing either. Look out below.

Now picture this. You are sitting on an out-of-control roller coaster.

The cars are going faster and faster, and there's nothing you can do. Up, down, left, right,

upside down. You are trying to brace yourself for what's going to happen next. As you're being tossed around, hanging on as tightly as you can, your stomach suddenly doesn't feel so well. Your stomach might

also not feel so good for a different reason in this next scenario.

Imagine being in a room surrounded by bodies.

As a medical student, you are inside a cadaver lab for the first time.

Bodies are everywhere, waiting for you and the other students to dissect them.

The smell, the bodily fluids.

Can you stomach what's going to come next?

Just being gross.

It's pretty simple.

I can tell you about it all day,

and until you experience it, you won't.

It doesn't mean anything.

Now visualize taking on the huge responsibility in the manufacture of a car that doesn't even exist.

On the production line, you must also find a way to keep your employees safe.

Unlike years ago, you might not need to worry about protective gear and hazards so much.

It's more about technology now.

I'll explain.
