Time might be the third constant. Then again, it might be an illusion. As the Buddhists say, "There is no time". š No doubt there is change, however, so out of convenience calling whatever this change is "time" works. Remember when we were kids singing "Too Much Time on My Hands" with Styx. Now it seems very much the opposite of that, where blink and a few years go by.
I love watches too. If I had the money, I'd buy a nice luxury watch. An Omega maybe. But I don't, so I just admire from afar. Maybe if Ray ever hurries up and makes us rich I can get one.
