> on my knee Wounds on/near joints are known to heal much more slowly because of the added movement-induced stress. In contrast, facial wounds heal particularly fast¹. For instance, I had a bike accident last September, which resulted in a small wound on my knee and several bigger, more severe injuries in my face. (I basically did a face plant.) The facial injuries healed within 2 weeks. Meanwhile, to this day people ask me what's wrong with my knee because while the wound has closed, I have severe scar tissue and it still looks like the accident had occurred only a few days ago. ¹) Not sure whether it's true but I read somewhere that this might have been selected for during evolution, since the face plays such a crucial role in communication.
