Is Aragorn as you pictured him?

[Sauron the White]

Gwathagor

Actually, a good hunter would clean himself regularly (e.g. bathe in stream) to reduce his scent, thereby making it more difficult for him to be detected by his quarry. The Native Americans, for example, were very conscientious about being clean before they went hunting;

Is this something that all hunters would do in every culture that you know of?
How often do you think this process would have been used by a hunter?
Does this not go against what we know of bathing practices by people during the Middle Ages and agrarian times?
How do you know that Aragorn did not bathe? Even when he was doused in the river after going off the cliff in TTT he certainly did not have benefit of soap and shampoo, hair conditioner, and a good blow dryer.

addition: just had my daughter and her husband over for dinner and he is a big hunter who was raised in a family of hunters going back several generations. He also teaches science. He said that bathing is not going to get you any results because your normal scents begin to emerge almost as soon as you dry off. He said a good hunter uses wind and learns how to stay downwind of an animal. Or, old school hunters used to use anjmal urine to cover their scent with fox or skunk being the preferred scent.
