I used to but when I started menopause I developed a habit of passing out after donation. After I had done it twice and hit the floor in a spectacular fashion, I was thanked and asked not to come again because I was scaring the other donors! I am now aged out.
I did, for many years....until they told me that my blood group (AB+) wasn't that useful! Only 3% of the population has it and people with AB group can receive blood from A, B and O donors. So....not really needed!
