What mistakes/oooppppssss have you made due to cognitive / memory issues ???

For the last few weeks at work, we have been gearing up for this big training session at work. It is my responsibility to have the new database set up, and all the user accounts created so everybody could log in (I'm a Database Administrator). OK, this is just routine type thing for me so I'm thinking no biggy - I had it all done on Friday and ready for users to begin training on Monday (training is ongoing this entire week).

During the day Tuesday, the vendor sends me a new "updated" database with more current data than what is in the current demo database...

Here comes my OOPPPSSS... I saw the email with a link to download the database, I completely FORGOT that there is a training session ongoing (in spite of the big build up) -- I was thinking - "I have time - I will do this RIGHT NOW !!!" I wrote over the database that the users were working in. I knocked everybody out of their training session - took the database down - and lost all the accounts. I initially wanted to cry (but didn't have the luxury of falling apart) - the phone started ringing - people start coming to my desk wanting to know what had happened to the their training sessions. It took me 35 minutes of sheer terror to recover the database that the users had been working in (thank heaven for backups) - and get all the users back in and training again. I felt like a fool, but for some reason - after the initial SHOCK it then struck me ridiculously funny (maybe my way of coping - I tend to see humor in almost everything).

BUT - this is also the kind of things that I have begun doing in the last year that scares me to death !!! If I had written over a Production database - I could be fired - on the spot !!! I cope by bobbing my head and saying things like "another blonde moment" or I am having a very blonde day - but I also know the serious implications and my co-workers and managers all know that in reality - these things upset me horribly - I just joke my way through things as a coping mechanism I suppose.

Anyway - that is one of mine.

Please tell me yours.... Make me feel better - I need to know I am not alone...
