This is a short video of a woman in virtual reality (anybody know what game that is?) who drops a grenade trying to throw it, and proceeds to run for cover in real life -- straight into a stone fireplace. Obviously, whatever virtual hit points she avoided in grenade damage she almost certainly made up for in real life pain, and I hope this serves as an important lesson to everyone. "And what lesson would that be?" Always dive away from virtual grenades, never run.
Keep going for the whole video.
Thanks to Linby, who agrees virtual reality related deaths are going to rise exponentially over the next few years.
