Hello Again Eyrie:

Not sure what to think of the eye or throat demonstrations. Would never consider doing the eye thing no matter what the point, too inherently dangerous....

Assume clenching the eyelids will meaningfully tighten the skin there, making it a harder surface, but not enough (cannot envision it) ever being sufficently hard that I'd allow anybody to push against anything until it bent....

Dumb, dumb, dumb...

Identical principle with the iron bar and the throat.... even assuming its an alternate angle (then we realize/perceive it to be) it is a really good demonstration... cannot figure out the mechancs that would make that work...

Rod is too high to press/utilize the sternum to initiate the bend. Neither had their hands on the thing, but even if they did

Love to hear that one explained!
Jeff
