Blood donors - show of hands? If not, why not?

[wtf?]

Would if I could, but pilots are discouraged from giving blood. I am a donor tho' and they can harvest whatever they want if the worst happens.

I've never given blood, I would consider it even though I dislike needles etc, but I they won't let me donate as there's a one in a billion chance that I might have the mad cow's

But I am an organ donor.

So whats the story with giving blood if you've had Tattoos? Is there a standdown period?
I got a little work done in Ireland, so curious to see if that has any effect on things.

Tattoos/body piercing: Donors must wait six months after having a tattoo or body piercing before donating blood. The reason for this temporary deferral is the increased risk of hepatitis and other infections associated with tattoos and piercing. Other similar procedures that may fall under this category include acupuncture and electrolysis.

Same, got a tattoo in New York in March
