Ok. I looked him up. He was doing Plasma apheresis, which is actually a much bigger deal.
They hook you up to a machine that takes your blood and separates out the components they are collecting and returns the unwated blood components to your body. It takes 1-2 hours for one donation instead of the half an hour for a whole blood donation. And you can do it more frequently.
So this guy is truly amazing. 1000 donations that are more difficult than a typical whole blood donation.
