The Dutch Windmills are a group of former boxing professionals whose ages range between 70 and 90 years. These strong Netherlands grandfathers are fighting every week in the boxing school Crooswijk in Rotterdam. They are not as fast as they were in their 40s and 50s, but they are still fighting very well, even after heart operations, like 78-year-old Toon Schurmann. The former Dutch boxing champion had his last professional fight 44 years ago, but once a week he gets a thrill out of taking some hard punches to the body.
