First of all, I… I was very lucky to get into a good lab and in… a good lab and in Cambridge, you see, because of these personal influences essentially and then, secondly, the problem we work on was a way-out one so there weren’t many other people working either on protein structure or any of these other things, so there really wasn’t an enormous amount of competition. It wasn’t as if lots of groups were… had got the technique and were all focused, you know, on… on the same problem so it was more relaxed in that way, and so there was more time, you felt you could take things more easily and was more social life. Although people have social lives, you know, even under these competitive conditions; they have games of softball and they have picnics and this, that and the other. There’s quite… quite a bit of… or… or… parties and so on. I’ve noticed that even though these people have to work very hard and have to get grants and so on, nevertheless, they do need some relaxation and they also will go off on holidays, mountain climbing or whatever and get away, which is very sensible. So, it… it really… it really kills you if you… if you try and keep your nose to the grindstone all the time and I think people realise that. They need a… a relaxation and a change and… and so on. You… you have to be careful you're not… don’t get into that habit of having to work every evening and every weekend and not take a holiday. You’ll soon find, you know, that your productivity goes down and you're not enjoying life as much.
