As for practical experience, I helped my grandmother with her oxygen therapy (though I don't anticipate that experience coming in handy in the future). I treated three burns, wrapped a sprained ankle, treated a hand caught in a door and I applied and changed bandaging (not including band-aids) more often than I can count.
Hikermor, I acknowledge my limitations and I have been on the lookout for a first aid class in the area. If there is one, I haven't found it yet. I hope my hands-on experience counts for something.
