Aaron Schau donates blood at the Loyola University Center for Fitness in Maywood, Ill. He became a blood donor after a blood transfusion saved his mother's life two years ago.
March is national Red Cross Month, and the Chicago area Red Cross is
calling on people to donate blood. Fresh blood is needed to help
replenish the local supply, which was diminished after severe winter
weather forced the Red Cross to cancel blood drives earlier this year.
