Gods, I really am out of shape... I tried to do some sit ups yesterday evening. If I held my hands behind my head I couldn't even get off the ground. I managed 10, before I had to rest for a few seconds.
"'Twas brillig, and the slithy toves
Did gyre and gimble in the wabe:
All mimsy were the borogoves,
And the mome raths outgrabe."
