OT but yes, he's
donated blood before. (It was before he slept with the hooker, which would mean he couldn't donate anymore, if he was honest on the application which I hope to God he is because I don't want Chris' possibly-STD-tainted blood getting donated because he lied about it.)
I've donated blood several times and from the survey there's really nothing that would disqualify Chris from being able to donate. The questions are mostly about the nature and recency of sexual contact (which would not have mattered to Chris prior to the hooker), recency and nature of any times traveled abroad, recency and type of medications taken, and other things that would affect blood content (taking things like heroin or steroids via syringe, coming into contact with someone else's blood, etc). People always ask this question, but really if you think about the nature of the donation surveys there's absolutely no reason why Chris
shouldn't have been able to donate, at least before the hooker.
