better 2,3 hours a day than once or twice a week
well i'm currently working at smurd (Emergency Mobile Service for Resuscitation and Extrication) on an ambulance because one of my colleagues had problems with his knee. But as a fireman we have all sorts of activities like ladder/drill exercises, or study what to do in different situations or practicing human rescue ('till 4pm when we're free and we can watch tv, hit the gym, sleep or play football in our backyard). Now as a paramedic working on ambulance i don't do those stuff..we don't have the time...it's maximum 1,2 hours of quiet then there is an emergency.
