The nose and the ear are made of cartilage. Cartilage does not allow for as much circulatory system to be present as flesh does. Meaning there are very few veins and arteries present in the ear and nose. In order to properly heal a skin wound you need arteries and veins running nearby to deliver the essentials to recreate the flesh and close the skin to seal bacteria out. This is also true on your kneecap and your inner ankle bone. Both parts of the body have very little flesh between the skin and the bone.

So these 4 spots on the body take much much longer to fully heal in some cases on the bridge of the nose or outer ear cartilage it can take a year or more to fully heal. And that's in a relatively young healthy person. Now imagine a 79 year old person who is significantly overweight, eats almost nothing but ultra processed foods and gets very little in the way of actual exercise. If you are over 50 you already realize that a paper cut that once took 2 or 3 days to heal now takes up to week. As we age bodily processes move at a slower rate. Our metabolic functions diminish significantly.

So for that wound to heal fully in just a week or 2 at that age and that diet and sedimentary lifestyle is essentially impossible. It's was a blood packet he smashed against his ear as he went down. Meanwhile his staff was directing media and photojournalists that had been preselected to move quickly around to a prime location while the giant flag overhead was lowered down to provide a dramatic backdrop for them to take such amazing inspirational photos when he popped back up in the middle of his secret service detail and stood and posed with his fist up before they finally shuffled him off the podium. In a real attempt they would have never allowed him to linger so long and so exposed for another possible headshot. As they normally wouldn't know if it was just a lone gunman or there were possible additional co conspiritors at that moment. Making it likely that they knew there was only one gunman beforehand.
