I am Werner Herzog, the filmmaker. AMA.
I’d like to add that when I travel by foot, I don’t do it as a backpacker where you take all your household items with you, your tent, your sleeping bag, your cooking utensils. I travel without any luggage and I do not travel, let’s say, the specific trail 2000 miles which is marked. I do traveling for very intense quests in my life. I do that on foot.
