You can't really see what happens, but you know it's heroic.

That's State Trooper Eric Devers, who leaps over a guardrail to save a truck driver that had crashed off the highway in Miami County, Ohio. According to the video's description:

An officer with the Ohio State Highway Patrol was honored this week for saving a semi-truck driver's life back in April. Dashcam footage just released shows trooper Eric Devers arrive at the scene of a crash and immediately sprint toward the driver. The trooper found the man still belted into his seat. Shortly after, his eyes rolled back into his head and he stopped breathing, the Ohio State Highway Patrol said.

The truck driver apparently had an atrial fibrillation, which is a quivering or irregular heartbeat that caused him to pass out while driving.

And hey! How cool is CPR? You should learn it yourself and become a hero like that guy there.

Certification and education classes are totally available near you.

It only takes a few hours, go ahead and do it.

FOX News reunited the two men during an emotional television segment.

We'll even forgive Devers for saying a pretty worn cliché.

You can pretty much say anything you want while you're saving someone's life.

Which was it for you?

From the video description:

I'm a professional opera, concert and choral singer that was diagnosed with a brain tumour (a GBM as it turned out). The neurosurgeon's advice was to do an awake craniotomy so that I could sing during the surgery (on June13th 2014) in order to avoid deficits after the procedure. The music neuro team of the UMC in Utrecht was also involved in order to assist the surgery. There is no blood or exposed flesh in the video.I sing two (first and last) couplets of Schubert's lied “Gute Nacht”: the minor - major transition in order to see if I can still recognise the key change.
All is fine until min. 2:40 when things start to get very interesting… It’s been more than a year since and I’m doing fine, continuing my professional singing career.

I'll never complain about my annual physical or a trip to the dentist again!
