Hehehe... minds me. That talk and slide show... that lad was the sfter dinner speaker at a house dinner (house = uni men's residence). Our Don's wife was a biology prof and she arranged for the talk.

One part of the talk dealt with worms from undercooked fish and seafood. Some of these worms live in the last quarter of the bowels. When the host is sleeping, they push their way partly past the anal sphincter and lay eggs. I shall stop there and not relay the remainder of the cycle of procreation. Suffice it to say that it involves itchiness in that region.

The speaker also said that if anyone thought they might be subject to such a parasite, they need only perform a simple task. Upon waking in the morn, they could pat a small piece of clear "Scotch Brand Tape" near the sphinter and subsequently fold it, thereby trapping any eggs, and submit it to our "Den Mother", as he called the Don's wife, in his rather austere English accent, for her analysis.

Well, our house had it's own dining hall, replete with a 72 year old cook who was often was forgetful. And, the kitchen served deep fried battered fish once a week. Out of 64 residents, 55 submitted said pieces of tape within two days and all tested positive.

The orange flavoured powder we were given to mix with water and drink daily for three days was tasty, but the lineups at the house toilets were excruciating.

Anyway, the bi-valves and bottom feeders in the Northumberland straight are extra tasty.
