I was just wondering...as dive pros (DM, Instructors), do you keep your first aid/cpr skills, rescue skills etc. up to high standards by practicing, taking different courses, doing drills etc...? Reason I'm asking is that for the common mortal who takes a first aid/cpr course, just like diving, will have poor skills if they are not practiced and refined on a continuous basis. It would be sad to here of an instructor, who might have superb diving and teaching skills, not being able to effectively deal with an emergency if one was to happen.
