Having not been an ogre for most of your life, you might be tempted to skip these articles and move straight on to technology. But few people walk around the earth knowing they’re a monster–if they knew, they’d stop being a monster. So what if you’re a monster? What if you make people feel awkward and uncomfortable?

Take a moment to peruse this stuff; you might be surprised at what is and is not an awkward hand gesture. You also might be surprised at how the littlest details affect billions of dollars in business each day. (30,000,000 presentations are delivered daily around the globe.
