In this case - blood!
The EFG tried to make her first blood donation today, and it was a struggle just to get past the dragon on the door [whoops, no, she was a "donor carer"]. These organisations are very good, and we have a great deal of appreciation for the excellent and very valuable work that they do, but when they put the most unwelcoming person at the door, you wonder why you bother!
She hadn't eaten enough, she hadn't drunk enough, I wasn't allowed to help her fill the questionnaire in [I was told off quite sternly - "this is a confidential document and it will be discussed only with the donor, behind a screen, in private"]....I felt most unwelcome, so I left with the YFG! I felt like saying, "I'm her mother!" but didn't.....
Then the EFG was passed through the system and had good conversations with much, much more friendly nurses, both of whom asked whether her mum was there, so she told them about the incident at the door, and that I had left. They were politely bemused, she said. They fed and watered her, and decided that she could give blood after all.
Except they then discovered that her veins are inaccessible, and said that she would not be able to give blood after all, and would have to be taken off the register.
The FH has given over 50 pints, his cousin has made his century and my sister over 25, so she had hoped to carry on in the family tradition.
I cannot give blood, and was quite squeamish even being in the room with all the people hooked up to the blood collection paraphernalia. I can cope with a little blood, like from a cut but not a quantity in a phial and it all makes me feel sick and faint. Not good. I can't even look at the nurse taking blood for blood tests at the doctor's. Bit useless on that front. Sorry, folks!
Having said all that, with the FH's history, we are all willing donors for organ transplants after we die, and we would of course recommend that those able to give blood do so if at all possible.
