American Red Cross in need of blood donors
The American Red Cross says there's about 7 million blood donors in the U.S. each year, but that's still not enough.
Officials say someone in the country needs blood every two seconds.
The American Red Cross is in critical need of O- blood, which is a universal donor, and B- because it's so rare.
A short health history and physical evaluation will determine if you can donate and it takes about 10 minutes.
