Five-time mixed martial arts champ Tito Ortiz matched up with United Blood Services last month to host the Ultimate Blood Drive IV, bringing in 285 donors at Metrocenter in Phoenix. Because blood can be separated into components to benefit several patients, those donations have gone to save more than 500 lives in Arizona hospitals. Before the event, Ortiz stopped off at a local gym to show a few moves to MMA fans Joshua and Jordan, 12-year-old twin brothers who endure a different kind of fight every day – Sickle Cell Disease.  While most kids their age are playing sports, Joshua and Jordan spend much of their free time at Phoenix Children’s Hospital receiving lifesaving blood transfusions.  So far in their young lives, more than 125 blood donors have become their heroes.
