A friend in college once inflicted this little ditty on me. Out of the blue, he said “Did you know that your tongue rests on the roof of your mouth, not the bottom”.
It took about a second for me to realize that this, to my surprise, is true.
Then he said “Congratulations, now you’ll suffer tongue awareness all day!”
I did.
Does anyone else have any annoying facts like this to inflict upon unsuspecting victims?
My tongue rests at the bottom of my mouth. My dentist keeps trying to change that, since it’s pushing at my bottom teeth, but I’ve been doing it all my life…
You breathe deeper when you’re aware of your breathing. At least, I do… breathe in, breathe out, GASP Yup.
Damn you Beer! You registered just to inflict us with that? Now I’ve got tongue-awareness. You sorry buhstahd. 
try this one - generally you only breathe through one nostril at a time - swopping over every couple of hours or so.
For me that’s beause one of my nostrils is permanently blocked - flippin’ hayfever!!
Grim
I didn’y realize a finger constituted hay fever… 
Cite please.
I only ask for a cite 'cause I asked my anatomy teacher this and she said it was a myth.
All the artists out there/here probably know these, but I still like 'em. The top of your ear, where the pinna is attached, is in line with the corner of your eye. The space between the tip of your nose & the bottom of your upper lip is the same as the top of your bottom lip & the bottom of your chin. These are average norms, your results may vary.
I dare you to try that on Jay Leno.
Smell is particulate in nature. Every time you smell something, it’s because little pieces of it are floating in your nose. Enjoy!
Your foot is about as long as the distance between your elbow and your wrist.
Make a fist. See the size? That’s supposed to be the size of your heart. Now open your hand flat – that’s lung-size. At least that’s what I heard.
ultrafilter, I really didn’t need to know THAT.
Oh, one more: if you want to know if the waistband of a pair of pants or a skirt will fit you and you don’t want to go into the fitting room, wrap the waistband (doubled) around your neck. If it fits your neck, it’ll fit your waist.
Independence Day and Halloween are always on the same day of the week, even in leap years. 
you can not lick your elbow
Does anyone take this at face value? I just tried, and then I remember that when I heard this years ago, I had to try then, too.
Heh. I sure didn’t–two seconds later, I was desperately attempting to make tongue contact with my elbow.
I once realize that when a big kid named Irving laid the worst gas I ever smelt.
Then I forgot it.
I hope I don’t see Irving again soon.
So if you walk into a toilet and can smell crap, it means that physical pieces of the crap are coming out of the bowl and into your nostrils? I thought it was just the gases that you could smell!
Yuck!
Uhm… samarm… in that instance I think it would be the gases you are smelling.
