On June 3, the world lost the GOAT, the Greatest of All Time,  Muhammad Ali. The  heavyweight champion died at a Scottsdale, Arizona hospital, after a long battle with Parkinson’s disease. Across the globe, people went into mourning for the boxer-turned-humanitarian, who spent the last years of his life visiting hospital patients, prisoners and the needy, bringing them his message of peace and unity.

I remember watching him fight on television. I thought he was one of the most powerful and interesting men in the world. That he had a heart and soul that could never be stopped. Sadly, I was wrong.

But his legacy lives on.  His widow, Lonnie, is calling on all citizens of the world to "Be Like Ali". She's starting a public service campaign in the champ's honor, asking people to give 75 volunteer hours starting on Ali's birthday on January 17, 2017, which will last the entire year.

“He often said ‘service is the rent you pay for your room here on earth,'” Mrs. Ali said. “The time has come for all of us to pick up the torch from Mohammad and shine our own lights on the places and people who have been in the shadows for too long.”

The official kick-off is coming up in mid-July with a several events planned, including one in Ali’s hometown of Louisville, Kentucky.

Muhammad Ali advocated for the poor and for peace. He supported the Special Olympics and research into Parkinson’s disease. The GOAT believed that service to others is part of what makes America a great country. In 2005, George Bush awarded him the Presidential Medal of Freedom, saying that Ali was both “a fierce fighter and a man of peace” and he had a “beautiful soul.”

Ali’s last public event in April, 2016 was at a Celebrity Fight Night dinner to raise money for Parkinson’s. We'll miss the GOAT, but we can still honor him — by Being Like Ali.
