I haven't donated blood since February. I stopped because my doctor told me because of some iron deficiency issues. I'd always just sort of dealt with it through supplements, but she wanted me to stop, or at least only go half as often. Then COVID, i haven't donated in almost a year, which is the longest I've gone in a long time.

I feel guilty about it. Donating blood has always been such an easy thing for me. My office is right next door to a hospital which is always having a blood drive. If I remember to drink enough water, I fill the bag very quickly. My veins are uncooperative, but the folks at the Red Cross where I donate are very good at getting the needle in easily. I had even managed to work out my supplements and diet that I was only getting rejected for iron every couple of tries, instead of every other try. I was generally managing four donations or more a year.

I did it because it was so easy for me and because it's meaningful to the community. High impact, low effort. It always made me laugh as a vaguely gruesome application of my basic maxim: that our duty in society is to share our excess (time, talent, resources) with others.

I expect I'll start again, post-pandemic. But in the post-commute world, I wonder how frictionless it will be.
