As of today, September 9, 2010, I am an "Old Fart" (R) : I ordered my first set of bifocals.
I've worn glasses or contacts since I was 15. Twenty-six years of wearing single-vision lenses has been good to me. But it's only been in the last few weeks that I've noticed that I don't need to sit quite as closely to the TV, computer screen.... or to have the hymnal or choir pieces quite so close either.
Welcome to your 40s, kiddo!!!
