And in January of this year, after meeting with doctors, seeking second opinions and running several tests, Lu received confirmation of what he admits he deep down already knew. He was living with Parkinson's disease.
But despite being given such life-changing news, that broad, infectious smile of Lu's has not left his face.
"All I can do is take what I have at the moment, live life to the fullest, be grateful for what I have today and not worry about tomorrow," said Lu, who was 28 when he received the diagnosis.
Lu's approach of squeezing the most out of life involves passing on his love for hockey to the next generation of players. As an instructor at The Rinks, Lu works with young kids learning the game through the Anaheim Ducks Learn to Play Hockey program, powered by Ryan Getzlaf and Corey Perry. He teaches beginners the basic fundamentals of skating, passing and shooting, all in a fun environment.
"The biggest part is just to have fun and show the culture of hockey," Lu said. "Enjoy the fall and learn how to get back up on your skates."
When the Ducks began seeking nominations for this year's 21st Duck, an honor that goes to a fan who shows "perseverance, character, courage and inspiration," Zavala got the idea to nominate Michael.
"He's not one to tell people [about having Parkinson's] because he's so optimistic about it," Zavala said. "What better way for him to finally feel confident enough to tell his story than by doing it with the Ducks."
When Ducks captain Ryan Getzlaf paid Lu a recent visit at Anaheim Ice to inform him that he was selected as the team's 21st Duck, the news knocked Lu off his skates - literally.
