Yes I learned the bowdrill as a young boy from an Apache. No, he was not Tom Brown's mentor, but a cowboy who taught me to ride horses. He then told me to keep matches on my person at all times LOL. There is a great deal of personal satisfaction learning these skills. You also appreciate the marvelous advances in equipment, as did our common ancestors worldwide. A "shaman" teaching me his celestial cosmology- " and what's that star? thats a satelite you dummie!"
