Leifkin woke up sweating profusely one morning earlier this week. "I said to my wife, 'I think I'm in trouble,'" Leifkin said. Marjorie Leifkin called 911, and paramedics realized that the situation was serious. "I didn't even have the chance to introduce myself and he said, 'Don't let me die, don't let me die,'" paramedic Kevin Duffy told WABC.
