Your comment is bullshit...! I would suggest that you BLOW ME... but you're gay and you probably would...! So I'm not going to say that.
dude you are seriously stupid , the amount of external injury is a very poor indicator of the potential for internal injury and that potential (not really relevant here)vastly increases with age by the way 60+.
I've been trying to make this point to them for some time... Even suggested that they try a safe way to experience what Zimmerman was experiencing but 20 times worse in Zimmerman's case so that they might understand why he feared for his life. They don't get it though because they've lived sheltered lives and they think that having your head smashed off the ground is irrelevant and not life threatening.
It is your non sequitur argument that is irrelevant to the heart of this discussion rather than the unfortunate and repeated head dropping that you have endured.
Muhammad Ali is a good example of induced Parkinson's. How many lacerations to the back of the head did he have?
