I am clearly aging. When I started working at my present job in 1987, our department had no computers at all, and, therefore, no password-protected security. Back in those days, I had no problem learning and recalling strings of numbers (credit card numbers, ID numbers, etc.) and adjusted quickly when a number changed. I chortled when the professors balked.
Security in those days depended much less on technology. When I started, the three keys I carried (office, clinic, outside door) provided all of the security the department needed. There were no electronic strips in name badges, no passwords, and none of the ubiquitous cameras. A few doors had punch-button codes that everyone knew. The most secure areas on campus could be accessed by calling a friend and being "buzzed" through a door.
Security has changed; many systems now require passwords. For example, to get to the first screen of our new medical record system, I sometimes need to log in three separate times using two different log in/password combinations. Every important website I visit requires a different password. And, of course, just when I finally get them all in sync, a screen pops up that requires me to change one of them. I currently carry a list of over 70 log in/password combinations. Too often, I forget to write down a new password and get locked out after making too many attempts to access a site.
Fortunately for me, one bit of security has never changed. When I walk into the operating room dressing area to prepare for surgery, the lock on my OR locker is the same one that I used in high school gym class from 1968 to 1972. The lock still works fine. And, best of all, I can remember the combination.
I know I am getting older. I can no longer remember new log in/password combinations when they crop up. I write them down and hope I can find my list when I need it.
But, the day I can not get into my OR locker because I can't remember the combination will be different. That event will be mark the day when I realize it is time to call it quits.
