I am sorry this happened to you, but it is surprising that it was not stored somewhere in your browser...that is very odd. Perhaps many of you can look through your profiles and histories to retrieve it. It may be secreted away in there. Fortunately, I was forced to recall my login when I used a foreign computer about three months ago....it brought the memory to the surface. We should all do mental "cross-training". Vary up your mental activities.....do a new one from time to time and do it deeply. Learn the basics of a new language. Use your non-dominant hand for tasks. Read Samuel Johnson essays. Try visual arts like sketching and painting. Go hiking on a decent trail. Travel to a new city. Read Feynman's lectures on physics. You get the idea.
