I honestly believe that as I get older, I'm getting dumber. I was having trouble getting one of my websites to come up. Turns out the index.html file was missing. I had to have someone else notice that for me. (Thanks E.) I used to be sharper.
I have caught myself believing television commercials. Fortunately only for a few seconds. An ad will come on TV touting something as "the best" and, for a few seconds, I'll actually believe it is the best.
A few days ago I was on the phone troubleshooting my DSL connection with a tech support guy. He asked me if I had another phone cable I could plug in between the modem and the wall to test the line. I said no. He suggested maybe I could use one that was attached to a phone in the house. So what did I do? I disconnected the phone line I was using! What the hell was I thinking? I never would have done something that dumb a few years ago. Thank goodness the guy called me right back and I'd plugged the phone back it. It only took me a second to realize what I had done, but still, I'd done it.
There are other examples, but my memory is going, too, so I don't remember them. But I do recall that there are many instances when I had to mentally slap myself.
By the way, I have noticed that I'm a little sharper when I take ginko biloba. I'd better start taking more!
