Give blood 🩸

My periodic reminder to give blood if-and-when you can. For all our tech capabilities, we still cannot synthesize blood in the lab. (As I recall, an unsolved problem is getting hemoglobin to bind only to oxygen (an important function that blood performs). See

Four times I have posted an image of the needle in my arm. This is the first time I’ve photographed the bag full of a pint of mine…

Reviewing from my first post from a blood donation: “Historical note: I gave blood for the first time as a college freshman … on the same day I received my first letter from Clare. :)”
