Not from cycling, but I lost a couple of passwords (and who knows what else, but the passwords I can verify) by bashing my head while drunk. The previous day I could log into the email accounts associated with them, the day after I couldn't. None of the other ton of passwords that I use for work were affected and I can still remember nearly all of my older ones. The only correlation is that both of the passwords I knocked out of my head were long standing accounts whose passwords I had changed in the previous month. I still know where roughly on the keyboard they were though.
