Some of us, indeed, are very very old, myself some thousands, I've lost count, of years, my old (and I MEAN old) friend Emma still older, I wouldn't be at all surprised if she'd taught the Facts of Life to the Earth Mother, well, anyway,as I was saying, these threads keep coming up, and I distinctly remember answering them before! These young people, just asking why, why, why, are we nearly there yet? So I just say, there's nothing new under the sun, cleverer kiddies than you havce asked better questions, why, I remember when they asked them in Latin! But of course, I was very drunk at the time....
