I’m probably a month late and thirty dollars short on this one. However, last month, an article in New Scientist detailed the observation of orangutans self-medicating with an anti-inflammatory topical balm. The observation of rubbing an ointment into the fur is also a newly documented type of self-medication for any non-human ape. I love this type of information. It shows once again that the vast majority of differences between humans and other animals are differences in magnitude, not in kind.
