I have been giving since age 18yrs.
Got my silver award about 6 yrs ago so not sure how many I have given now.

Being a nurse you see how much is used within hospital environment so wouldn't stop till they tell me I have to.

Just remember to eat and drink something before you go.. collapsed once when I didn't.
and don't light up a fag as you walk out...son collapsed in doorway on way out doing this! lol
