What's under this plate?

I would love to go around and answer just the titles of the threads all day long...
I think the last one was Trail Beast asking why is it so hard LOL.. of course my advice was if it's lasted more than 4 hours to seek medical medical attention... That one still gives me a chuckle when I think about it..
If it lasts more then four hours I'd seeks professional help all right...but I doubt I'd call a doctor
