On a leafy boulevard in downtown Havana, a man is beating himself with a sledgehammer, on his wrists, elbows and forearms, drawing a crowd of passersby who gather to film the spectacle with their phones. What shocks the crowd is not the apparent self-mutilation, but rather the fact that he appears to come away unscathed. Cuban "Ironman" Lino Tomasen said he once aspired to be the next Mike Tyson, training to become a professional boxer by subjecting himself to millions of blows with the hammer, and eventually moving from the Caribbean island to fight in Mexico City. "I had 27 matches won by knockout, but I retired because in the last of them I fractured the skull (of my opponent) and he died instantly," the stocky Tomasen recalled in an interview with Reuters in Havana. "I gave away all the money I made in my fights to his family," he said, estimating the sum to be over $100,000, a huge amount of money for most residents of Cuba. "I vowed never to fight again." Tomasen has since written off fame and fortune, and makes a far more modest living on the streets of Havana and nearby beach communities, collecting tips from impromptu shows.
