Fingers too chilled to work the controls - I can relate to that. My memories are of motorbiking, though. Back when I was younger and even dafter, I'd think it normal to leave work at 6pm or so on a Friday afternoon and go and spend the weekend with London friends, using the motorbike - I lived in Yorkshire, so the ride was about 200 miles from North to South. Many times, going for fuel, I couldn't unclench my fingers and use the front brake. Had to slow down on the back (foot) brake and grip the exhaust pipe, gloves giving off smoke for four or five minutes, before I could work the petrol hose!
