The dangers of solidified dihydrogen monoxide.

I was discussing the dangers of dihydrogen monoxide in #yuletide today.

One of the particularly degenerate people there told us all that in her youth she had used slabs of solidified dihydrogen monoxide recreationally; the practice also involved the use of sharp blades. Her level and type of use dulled her sense of self-preservation and eroded her ability and willingness to dodge projectiles.

It didn't help matters that there were government-sponsored facilities that enabled her use, nor the media coverage glorifying the practice.

She doesn't use any more, but it's left her with a taste for violent sports.
