Frankly I was tending to discount Trump's explanation.
Took awhile but I did find this from 2003.. Someone had asked how come his ears bleed when he's really angry. One response was:
"A surge in blood pressure caused by your rage would be my most likely guess as well. The capillaries in the nose are quite fragile and can burst easily, but I've never heard of an ear-bleed in this context."
Actually I experienced something similar at my age.. I recently got very angry and the next day I noticed the worse purpura (hemorrhages in the skin . . . that result in the appearance of purplish spots or patches) that I've seen so far. I kind of thought there was a connection. So right now it's slowly being removed and carried off for disposal and restoration of skin.
Great find, Bill!
