The other one I recall, but not many will, was that we had a learner in Colchester, in the mid/late 90s, he was a youing guy, about 22/24 if that, was learning the Ipswich panel, had been on Ipswich about 4 days or so, and doing really well, he picked things up quickly, one day said he had a headache, so sat down for a while, in the end he was sent home, as there is no point trying to learn if you are not 100% especially Ipswich !
Next morning we had a phone call to say he had passed away overnight.... talk about stunning everyone into silence that day !
