Pay the man...Highlights from the Oculus Rift's Health and Safety guide

Discomfort

This is the best section—if only to highlight how our bodies are rubbish and frail and we should all have our minds uploaded into indestructible robots. It starts with a worrying list of possible symptoms, including "involuntary movements", "disorientation", and "increased salivation". It's important to know why you're salivating, though: sure, maybe it's an impending sign of projectile voms, but maybe you're in a VR restaurant looking at a nice steak.

Then comes the terrifying prospect on virtual reality exposure:

"Just as with the symptoms people can experience after they disembark a cruise ship, symptoms of virtual reality exposure can persist and become more apparent hours after use. These post-use symptoms can include the symptoms above, as well as excessive drowsiness and decreased ability to multi-task. These symptoms may put you at an increased risk of injury when engaging in normal activities in the real world.

I think what they're trying to say is that after I tried Half-Life 2 on the Rift for the first time, and then later stood at a train station, battling the cold grip of unbearable nausea, I was wrong to use the platform's vending machine.
