NYC's Dr Jack Berdy offers a botox treatment called "pokertox," which freezes parts of the face implicated in poker "tells" -- nonvolitional expression-changes that signal your opinion of your cards to your adversaries.
Some players look at their cards and ‘‘might raise their eyebrows or raise one eyebrow’’ if they do or don’t like what they see.
“Some squint, or furrow their brows,’’ Berdy said.
“We can inject Botox appropriately’’ so the other player doesn’t get the message that they’re angry, disappointed or happy.
“What someone sees across the table is no movement,’’ he said.
Remember the TSA's plan to turn mall-cops into mind-readers by teaching them to read semi-mythical "microexpressions" and so detect terrorists? Even if it worked, anyone wanting to foil it could presumably plump for some terror-tox injections and pass through the TSA look-into-my-eyes-and-swear-you're-not-a-jihadi checks smoothly and without batting an eyelash.
