It's so amazing that it's almost miraculous!
I got sent to A&E with stomach cramps - work weren't too impressed when I collapsed in the corridor... Kept me in for 4 hours, gave me something intravenously (no idea what, wasn't exactly coherrent at the time) then sent me home and told me to STAY IN BED for 2 days. I could barely even move the next day, let alone run any where.
Some people might wonder if there was a teensy weensy bit of exageration going on somewhere.
Ho hum.
