  |  | Well, two actually, but at least I got them over with at a relatively young age...
At sixteen I went on a canoe trip down the Rhine in Switzerland. We'd obtained information that there was a canoe ramp at one point on the river, so when I saw a sign saying "Kahnrampe" I confidently paddled toward it. My first suspicion that all was not entirely well came when I saw a flipped-up panel saying "frei" on the back of the sign. I then saw the ramp: a series of rollers entirely clear of the water; which was quickly flowing through a half-open sluice gate immediately to the left...
Suffice to say that I found myself wedged in a corner, my back against the iron sluice gate on one side and a concrete wall on the other, with the deck of my boat pressed against my chest. The boat came to a halt when the stern hit the concrete step at the bottom. At which point all would have been fine, except for the view of the surface of the water: two feet above my head.
I don't know how long I was stuck there, just that it was long enough to conclude, in the words of DNA, that life was not going to be troubling me for much longer: a strangely calm and detached feeling, it has to be said. By pure chance at that point the hull of my boat buckled slightly and the water pressure forced me through the gate into the weir below.
When I got home, I fixed the boat, paddled it once to prove I could and then sold it: I've not done much canoeing since. My friends probably got a worse shock than I did: I was the good canoeist, and knowing the Swiss reputation for hydro-electric power, once I disappeared they expected to be looking for something with the consistency of steak tartare. Fortunately, it was just a weir.
A few years later, after my first year at University, I had a summer job with the British Steel Swinden Research Labs in Rotherham. One of the experiments I was doing involved corrosion fatigue tests in a Hydrogen sulphide atmosphere. This meant evacuating a 1 cubic foot test chamber, then admitting H2S to about 0.2atm. Little did I know that one day I had managed to total the pressure gauge, so the next time I was admitting the H2S, there didn't seem to be any going in. So I cranked the valve right open, to be rewarded by a hissing noise and a bad smell.
Which quickly went away.
Apart from its "rotten eggs" smell, hydrogen sulphide has the property of binding to certain receptors in the central nervous system, so that above concentrations of about 100ppm you can't smell it. By 300 ppm and rising you will have difficulty seeing, hearing, thinking or indeed, breathing. One thousand ppm is almost instantly lethal.
At this point I decided that going outside for the gas mask was a higher priority than trying to finish closing the valve. I made it outside the room before everything went all wiggly like a Blake's 7 transmat effect and I came to sitting on the floor. Apparently the detector had been sounding alarms loud enough to wake the dead, but I never heard them.
For a while the thought that I was immortal warred with the idea that the third time is the charm...

  |  | Mid-eighties as I recall. Apparently at first the fares went in 1p steps, but 5p bands were brought in because little old ladies were holding up the buses haggling over a pennyworth of ticket price...
I think the Swinden Labs are still there, although they may have been sold off when British Steel became Corus. I remember trying to find my landlady's place on Herringthorpe Valley Road, not realising quite how long it was...
I've never actually been to Coventry, although as I used to live in Birmingham, I've gone past it a lot. Although if it makes you nostalgic for Rotherham... LOL
