Damon Friedeurg, Orlando, donates blood at the Oneblood donation center in Orlando, Fla., while his son Kellen, 12, who has to wait four more years until he is 16 to donate, discusses the process with his dad on Monday, June 13, 2016. The center took in 5000 units yesterday, helping to replenish the state supply. An appointment system has been set up today to help avoid the long lines and hours of waiting for those wanting to donate. Curtis Compton / ccompton@ajc.com
