Glad you’re okay, that sounds like a very big deal! I hope I’ve helped someone (at over 6 gallons donated, I should hope I did!) and I also really hope I never need any transfusions… I don’t know how I became a bit of an advocate for blood donations, but I really have…
(One lady at work was always harping on me to donate my hair, which I can’t, because 1 - it’s too grey and/or 2 - it’s dyed and 3 - I rather like having long hair. I finally shut her up because she never donated blood, and there are synthetic wigs and blood = life or death, so there!)
