answer:I think the only thing I can say was fate or coincidence was when I was at university and I was supposed to be going to a remote corner of an island for 6 weeks as part of my course. This is the kind of place where our equipment could only get there via helicopter and it was a walk in the wild for a couple of hours to this windswept place. Anyway I had been having problems with my knee a few months before and out of the blue I woke up one morning and decided I was not going to go to this distant place. I had no idea why I felt like that but I cancelled there and then. To cut a short story even shorter the day after I should have arrived there my knee basically imploded and I was unable to move followed by reconstructive surgery the next day and months of physio. Apparently it could have gone at any moment, but if I had not cancelled I would have been stranded in agony and needed all kinds of things such as the RAF rescuing me. Instead, I was 1 mile from the hospital and I was able to sleep in my own bed and then get tea and toast after the operation.
