Giving blood or being a fan? 2009 - Milwaukee, WI
Eighty year old Jim Becker's road to becoming the 12th member of the Green Bay Packers Fan Hall of Fame started in 1952. Married with 11 children he didn't feel his family could spare the money for Packer tickets so when he found a pint of blood sold for fifteen dollars, he decided to give blood four times a year and use the money to buy tickets for all home games. In 1970 Jim was diagnosed with hemochromatosis - a blood disorder that results in a large amount of iron in the bloodstream. The treatment is to frequently donate blood. Doctors told Jim his blood donations were a stroke of genius that probably saved his life. Jim's father died as a result of hemochromatosis when he was only 43 years old. Makes one wonder if going to the games or becoming healthy urged Jim to give blood. Maybe both.
