I don't have a response for the bolus thing, I just wanted to say.... "Good for you"!!
I so wish I could give blood, but I can't. We had a Blood Run here about 15 years ago and I went in with the rest of our friends and my husband to give blood and I can't give.... EVER! I have a Mitral Valve Prolapse and in order to even have my teeth cleaned, or anything consisting of bleeding, I have to take an immense amount of antibiotics. So they told me nope, and not ever.
