I dunno whether it's ADD or just that I'm on the backside of the aging curve, but, sometimes I'm forgetful. Today, I had a particularly iffy moment. I was reading a web page that made me go, "a hah! I need to look something up." Unfortunately, it was only very tangentially related to what I had been reading. At any rate, I clicked <CTRL-T> to open a new tab. As I was moving my cursor up to type a search term (or, perhaps even a URL), I forgot what I was going to type. Because what I wanted to type was only barely-related to the page I'd just been viewing, that page failed to bring back to mind what I'd forgotten in that brief instance.
