Lou Spizzirri spoke publicly for the first time Thursday from his bakery business in Bolton, two weeks after undergoing a double bypass at Toronto's Sunnybrook hospital, where a team of doctors tweeted as they operated on him.

He agreed to have the entire surgery, including pre-operation procedures, tweeted live. The hospital says the experiment was meant to promote heart health awareness.

Until Thursday, Spizzirri had not seen any of the footage of the operation. When he finally did, he spoke about having it on his birthday and "getting a second chance to be reborn on the same day."

"I feel great," the Caledon resident said. "I get fatigued quickly, but I feel great."

Spizzirri spoke to CBC's Steven D'Souza about making medical and social media history.

"Considering the amount of work they're doing there, I'm surprised I'm even standing, walking, right now," Spizzirri said as he watched the footage with his wife, Rosa.

He said he was compelled to make lifestyle changes a year ago, when a cardiologist told him "it was stop smoking or die," and said he might go fishing more to relax.
