A Severe Shortage of Blood!

Blood donation bags at a blood drive in
Rochester Michigan on March 24, 2020.
My name tag at the blood drive.
I had a difficult time taking this selfie: one hand holding my
phone, the book balanced on my chest, and a needle in the other arm.
The best part of blood donation.
After giving blood. My daughter Stephanie,
who also donated, took the photo.
