Blood donor wins Super Bowl tickets LAFAYETTE, Ind., Jan. 30 (UPI) -- An Indiana woman who has donated 143 units of either whole blood or platelets since 2003 said she was shocked to win Super Bowl tickets. The Indiana Blood Center said Carol Sikler, 50, of Lafayette gave blood frequently enough to qualify for the contest, which was open to anyone who donated blood or blood products four or more times in the space of three months, and she has now been announced as the winner of two tickets to Sunday's Super Bowl XLVI in Indianapolis, The Journal & Courier, Lafayette, reported Monday. Sikler said she has been giving blood in a bid to "break even" for the blood made available to her husband Chuck during a pair of lengthy hospital stays prior to his death in 2003. She said she recently surpassed her goal and decided to keep donating. It's a way for me to do something for someone that can't ever thank me or pay me back personally. It's giving without expectation," she said. Sikler said she was shocked to win the contest. "I'm not the kind of person who wins things," she said.
