Blood Donation Rejection

I tried to give platelets at the NY Blood Center today. I was rejected because my hemoglobin was 12.4 and 12.5 is needed. I wasn't upset but was quite impressed by the number of similarly aged people in there also donating platelets. Most of the time when I donate platelets there is a good twenty year age difference between the other donors and I. After years of seeing no one within two decades of my age donating blood or platelets, it was so good to see other people my age donating.
