June 14 is World Blood Donor Day, so consider this your PSA to make an appointment at a nearby donation center. You’ll find this DCist editor at the American Red Cross at 2025 E Street NW this afternoon, downing free OJ and cookies. The Red Cross always has plenty of appointments open — you can probably even stop by today, but you’ll want to call 1 (800) GIVE-LIFE to check before you head down. For other locations, type in your ZIP Code here for donation centers all over D.C., Virginia, and Maryland. First-time donors can read here about the process and eligibility requirements; those who need a little convincing can read here about why blood donation is needed. (For example: A car accident victim can require up to 100 pints.) Of course, if you have Type O negative blood, the universal donor, your help is always needed. Don’t forget, there are free cookies in it for you.
