Just a quick pop-in. I saw this video on YouTube yesterday and got a hilarious mental image of teenage shape shifters huddled around a school computer like they were watching something ilicite. Then one youngster in the back murmurs, "Oh, so that's why monkeys lick each other like that! Weird."
Sorry, I wrote this on my phone in bed, so I can't embed the vid. The link is perfectly work-safe, though. It's from one of my favorite YouTube channels, SciShow, and talks about why humans kiss. TTFN!
