let me tell you a story:
Circa 1969 and I'm a humble vet student. I have become infatuated with a lady colleague and madly keen to take our relationship further. I finally get an invite to Sunday lunch with her parents and dress myself in my best (only) finery and duly present myself at their spotless mansion in Kent. I'm suitably nervous and trying hard to be the suave sophisticate that might be considered a valid suitor... except for the nerves. The sweating gets worse, I start to get awful gut pains all due to the nerves and spent most of the day running back and forth to their loo with unnatural sounds emanating from that smallest room. It was a trial for this pale and shaking lovelorn student
Somehow I make it through the day and return to my lonely garret room in North London (and it was a garret ) hoping for that terrible experience to subside and knowing I have lost my first love forever.
Around 2 am I have another need to visit the bowl of doom.. and this time pass several 10" Ascaris Suum.. worse perhaps because I was able to identify the things and had visible experience of how they look inside pig guts. I freaked - leapt into my car and went looking for a doctor. I hammered on every door with a brass plate indiscriminatly waking up a couple of architects and other assorted professionals before actually finding a doctor - who I'm glad to say was actually quite sympathetic and gave me a chit for the all-night pharmacy.
Cook pork well - I blasted well do!!!
