End of an era: Boxing legend Muhammad Ali passes away at 74

“I'm the greatest thing that ever lived! I'm the king of the world! I'm a bad man. I'm the prettiest thing that ever lived.”

The ‘People’s Champion,’ Muhammad Ali, passed away at the age of 74 in the state of Arizona, USA.

Described by many as the ‘Greatest of All Time,’ he had been struggling with respiratory complications for a time. On Friday, the legendary boxer breathed his last at a Phoenix hospital, a spokesperson confirmed to NBCNews.

Ali’s stellar record of 56 wins from 61 professional fights, 37 of them knockouts, have become part of his legacy.

As his 32-year battle with Parkinson’s disease comes to an end, Ali is survived by his seven daughters and two sons. His last rites will be carried out in his birthplace of Louisville, Kentucky.
