Todd Tewksbury was just 27 when he had a cardiac arrest.

“Very lucky to be alive,” said Tewksbury.

Todd was in great shape with no symptoms. He was on a daily run when his heart stopped beating.

“It can happen to anybody. Doctors attributed it to a virus I caught that can be carried in a common cold virus,” Todd told CBS3’s Stephanie Stahl.

He was saved by strangers, people knowing CPR and how to use a AED can be the difference between life and death.
