A day of exercising at Variety Village took a terrifying turn for one Toronto man.

Daniel Terbenche was working out like normal one day in February, walking laps around the track, when he sat down on a bench to rest.

That's the last thing he remembers.

It turns out that Daniel had suffered a heart attack. Thanks to the actions of four employees who saw what was going on, he's still around to talk about it.

"There was no warnings, no chest pain, no breathing problems that I remember. Just bang," Daniel, pictured here wearing a striped t-shirt, describes.

He returned to the Village Wednesday to pay tribute to the men who saved his life.

"I just want to say thanks for saving my life. Thank you from the bottom of my heart," the 63-year-old told the crowd.

The four men used a defibrillator donated by the Mikey Network, and got their training from the Toronto EMS Safe City Program, but never dreamed they'd be called upon to use it.

"I wasn't nervous at the time," explains Joseph Rosgen.

"I wasn't really thinking: Should I do this? Should I do that? I just went and did it, just kicked right in," the hero continued.

"The machine will actually tell you exactly what it wants you to do and where to place the pads. It's really...I want to say defibrillation for dummies," fellow rescuer Shane Risto added.

Risto, Rosgen and two other men received medals from the City of Toronto for saving Daniel's life.

Hugh Heron, CEO of the Mikey Network, was also on hand.

"In my opinion, there should be a defibrillator everywhere there's a fire extinguisher. More people die from heart disease than die from fires," he proposed.

Daniel couldn't agree more.

"The difference between having a defibrillator available and not having a defibrillator available is the difference between my fate and my father's," he said.

Daniel's father died of heart disease several years ago.

Check out the warning signs of a heart attack:

• Sudden discomfort or pain that does not go away with rest
• Pain that may be in the chest, neck, jaw, shoulder, arms or back
• Pain that may feel like burning, squeezing, heaviness, tightness or pressure
• In women, pain may be more vague
• Chest pain or discomfort that is brought on with exertion and goes away with rest
• Shortness of breath
• Difficulty breathing
• Nausea
• Indigestion
• Vomiting
• Sweating
• Cool, clammy skin

If you are experiencing any of these signals, you should:

• Call 911 or have someone call for you. Keep a list of emergency numbers near the phone at all times.
• Stop all activity and sit or lie down, in whatever position is most comfortable.
• If you take nitroglycerin, take your normal dosage.
• If you are experiencing chest pain, chew and swallow one adult 325 mg ASA tablet (acetylsalicylic acid, commonly referred to as Aspirin) or two 80 mg tablets. Pain medicines such as acetaminophen (e.g. Tylenol) or ibuprofen (e.g. Advil) do not work the same way as ASA (i.e. Aspirin) and therefore will not help in the emergency situation described above.
• Rest comfortably and wait for emergency medical services (EMS) (e.g., ambulance) to arrive.
