I remember a blood donation which was quite special.
Whenever possible, I donate by a method called apheresis. I don't know if you've tried it, but it allows you to donate only specific stuff from your blood (I usually donate platelets and plasma).
They connect you to a machine which removes a bit of blood, filters what you are donating out, adds a liquid solution if required and returns it to your blood. Then repeats and repeats and repeats.
It's a long process but it allows donor to actually donate more.
Well, technical explanation over xD
So this one time there was a politician visiting and they wanted to show him the machine, and they asked me (cause I was quite a veteran and they knew I did not feel uncomfortable by these things) if they could dissemble the machine aesthetical parts so we could see all the filtering while it was happening.
I agreed, with the only requeriment that I wanted to be able to see too!
A while later, some technicians from the lab (which was downstairs) came and told me "Oh, so you don't really care? Cause we wanted to see it operating if you don't mind, in all these years working here we've never seen it!"
And there we go again xD
It was quite a weird situation.
