LifeHackerIf you have a particularly strong gag reflex, this popular dentist’s trick can help distract your brain and save you the discomfort (and embarrassment) in seconds. This isn’t a new discovery, but it’s one many of us hadn’t heard of before, so we thought it worth sharing. If you’re in a situation where something is setting off your gag reflex (dentist’s offices are one of the most common places), just form a fist with your left hand, squeezing your thumb. The folks over at Reddit’s Ask Science forum deliberate as to why this is, and they point to a 2008 study that shows it to be effective—not to mention lots of anecdotal evidence on the internet—but whether it’s an effect of the nerves in your hand or just a distraction, it looks like it’s a pretty useful trick. Of course, it’s a bit different for everybody, so your mileage may vary, but it’s something to think about the next time you’re sitting in the dentist’s chair.

We interrupt your regularly scheduled Penn State programing to talk about chicks deepthroating. Lifehacker can play the PC card all they want and keep dropping “dentist chair” references but we all know thats code talk for “giving blow jobs.” If you ask anyone on this planet “whats the first thing that comes to you mind when I say gag reflex?” all 7 billion people will say “sucking dick.” Nobody’s thinking about the fucking dentist.

Now listen this could very well be an old wives tale. Maybe there’s some sort of crazy acupressure going on and squeezing your thumb lets your throat open up. Probably no chance. Maybe like they said its just like a placebo effect and you’re thinking about your thumb instead of gagging and you relax. Thats most likely. Or maybe its not true at all. All I know is that the next time I’m getting a blow job I’m whipping out a pair of mittens and I’m throwing them right on her. Maybe even wrap her hands up and give her one of the offensive lineman clubs. Squeeze those thumbs darlin! We’ve got a long way to go!

Just kidding I’m not even sure its physically possible for me to trigger that reflex. But for real girls, tell me the next time you wanna make your man happy you’re not at least gonna secretly give this a whirl. Fellas do a little inspection next time you’re getting a blow task. You see a chick squeezing her thumb shes a keeper. Gotta respect the effort.
