Today I considered pouring a cup full of hot coffee (straight out of the kettle) on to my forearm.
The test would be to see whether I could hold my arm in place and resist the reflex to pull it away from harm.
The next trick would be to ignore the first-aid recommendation to shove the burn under cold running water. I’m pretty sure I’d end up with an exciting scar to show my grandchildren.
Some deeper instinct stayed my hand.
The Waffle Group 
How very Fight Club.
I am given to wonder if the Waffle Master has actually done this, and thereby damaging himself so severely as to not be able to blog anything about it.
A conundrum, indeed.
