What is the strangest substance that scientists know about?

You're confusing lichen with triffids, which Wyndham did indeed make up.

Yeah, you may be right! I've all of his novels -- I like them all! "The Day of the Triffids" - - a sort of scary novel. I find most of his stuff has an eerie yet very realistic quality (once one goes along with the plot's main premise).

:)

My fave yarn of his is The Chrysalids, set in a post-apocalyptic dystopia, supposedly following a global nuclear war although not specifically stated as such.

One other thing can...tardigrades. They are so cute.

That creeps me out tremendously.
:)

They are everywhere...maybe in you pubic hair...but not to worry, they are harmless...LOL.

Well, my pubic hair seems to be healthy, so they must be good for me!
:)

Unlikely, unless WQ's pubic hair is permanently moist. They're called "water bears" for a reason. They can survive being dessicated, but that generally only happens when the water they live in evaporates, they won't seek a dry environment.
It's more likely that a few are floating around on your corneas. This post was edited by Slartibartfast at September 19, 2018 6:52 AM MDT

Thank god I'm at least safe from that then...:(
