Violent Video Games May Increase Your Pain Tolerance

Original image

Worried you might be tortured and interrogated soon, but don't want to break down too quickly? Well then, better grab a copy of Resident Evil, Doom, Gears of War, or whatever your favorite violent video game happens to be because, as it turns out, it might just help you hold out against pain longer.

Researchers from Keele University have discovered that violent games could potentially be used to help relieve pain. And no, not all video games have this effect; sports games, for example, don't increase your pain tolerance.

The study found that volunteers who played violent games could hold their hands in ice-cold water for 65% longer than those who played a non-violent golf game. They speculate that this is because our minds respond to virtual violence the same way they respond to seeing real violence, thus increasing our heart rate and our pain tolerance as a result.

Belly flops are the least-dignified—yet most painful—way of making a serious splash at the pool. Rarely do they result in serious physical injury, but if you’re wondering why an elegant swan dive feels better for your body than falling stomach-first into the water, you can learn the laws of physics that turn your soft torso a tender pink by watching the SciShow’s video below.

What's the Saltiest Water in the World?

Saltwater is common around the world—indeed, salty oceans cover more than two-thirds of the globe. Typical saltwater found in our oceans is about 3.5% salt by weight. But in some areas, we find naturally occurring saltwater that's far saltier. The saltiest water yet discovered is more than 12 times saltier than typical seawater.

Gaet’ale is a pond in Ethiopia which currently holds the record as the most saline water body on Earth. The water in that pond is 43.3% dissolved solids by weight—most of that being salt. This kind of water is called hypersaline for its extreme salt concentration.

In the video below, Professor Martyn Poliakoff explains this natural phenomenon—why it's so salty, how the temperature of the pond affects its salinity, and even why this particular saltwater has a yellow tint. Enjoy:
