Sufficiently well to see Johnson and Truss and then two or three days later, she’s dead. I thought, that’s fantastic. That’s something to celebrate. That’s a great death.

I remember what George said and vowed that rather than let Alzheimer's take me, I would take it. I would live my life as ever to the full and die, before the disease mounted its last attack, in my own home, in a chair on the lawn, with a brandy in my hand to wash down whatever modern version of the "Brompton cocktail" some helpful medic could supply. And with Thomas Tallis on my iPod, I would shake hands with Death.

And even if my voice goes before I do, I shall continue to write polemics against religious delusions, at least until it’s hello darkness my old friend. In which case, why not cancer of the brain? As a terrified, half-aware imbecile, I might even scream for a priest at the close of business, though I hereby state while I am still lucid that the entity thus humiliating itself would not in fact be “me.” (Bear this in mind, in case of any later rumors or fabrications.)

Sometimes when I’m on a plane, as I often am, the weather is rough and we’re worried about going down. I think: If I hold the hand of the person next to me, I’ll be holding everyone’s hand. Like my dear friend, the late Wilma Mankiller, principal chief of the Cherokee Nation, I want to know: I’m going to the other side of the mountain.

Being together with the ones I love on a Wednesday afternoon, washing the dishes, taking the garbage to the bin under a gray sky, hearing the distant sounds of children from upstairs, turning around and suddenly looking into the eyes of the one I love. It is the feeling of being alive I’m talking about. And of being in love.
