Radek Sýs is a 38-year-old police officer from Brno, Czech Republic who has donated blood and plasma 93 times for free. He started donating when he was 25 years old at a hospital in Boskovice. For his numerous donations, he has received bronze, silver, and gold Jánský plaques as well as a gold cross award. Jánský plaques are awarded by the Red Cross to recognize frequent blood donors in the Czech Republic and Slovakia. Donating blood involves giving nearly half a liter of blood through a sharp syringe, which most donors do not find painful, especially with the company of friendly nurses.
