I had donated 9 times between the time I started at 16 until I graduated high school two years later. I got an award for it. I'm still donating when I can. I am one pint short of two gallons.
When I was a bit younger, my parents would go and donate all the time. Later, when I started donating, my dad and I would go together. He has B positive, which is very rare, and I have O positive, which is also rare, so they want us to donate whenever we can.
We would race to see who could squeeze pint fastest. He would beat me but only by a few seconds.
