When did you have your appendectomy? Apparently they now do a laproscopic procedure through the belly-button, and recovery is pretty damn fast.
In 2006. And it was in a hospital in East London, which Limey may concede might not have been quite up-to-date on the latest technology. Or the latest techniques, such as properly re-inserting a patient's IV in the middle of the night, so that he doesn't wake up a few hours later to find his own blood soaking half his bed.
I went to Spain just over a week after the operation, and I kept having to force myself to walk slow, which was annoying because I was there solely for sightseeing, which meant lots and lots of walking. I can't imagine trying to deliver a pitch at 90+ MPH just two weeks after the operation, but as you imply, perhaps times have changed.
