The terms "idiot" and "lunatic" were acceptable diagnostic terms in England up until 1959. "Imbecile" and "feeble-minded person" were, likewise, listed as official categories in the 1913 Mental Deficiency Act. England has always lagged a bit behind in discarding outdated terms for the disadvantaged. When I was there in 1980, it was still possible to shop for used clothing at the local Spastic Shop. That is, compared to the United States, where it takes, oh, about twenty-five minutes for a diagnostic euphemism to become a conversational faux pas.

I began thinking about my skeleton, this solid, beautiful thing inside me that I would never see.

Every mode of travel has its signature mental aberration.

I am very much out of my element here. There are moments, listening to the conversations going on around me, when I feel I am going to lose my mind. Earlier today, I heard someone say the words, "I felt at one with the divine source of creation." Mary Roach on a conducted tour of Hades. I had to fight the urge to push back my chair and start screaming: STAND BACK! ALL OF YOU! I'VE GOT AN ARTHUR FINDLAY BOX CUTTER! Instead, I quietly excused myself and went to the bar, to commune with spirits I know how to relate to.

For the scientists, they're kind of puzzled and pleased that somebody finds their work interesting. It makes it fun for me. I feel like I've sort of turned over a stone that hasn't been turned over.

The nobility of the human spirit grows harder for me to believe in. War, zealotry, greed, malls, narcissism. I see a backhanded nobility in excessive, impractical outlays of cash prompted by nothing loftier than a species joining hands and saying “I bet we can do this.” Yes, the money could be better spent on Earth. But would it? Since when has money saved by government red-lining been spent on education and cancer research? It is always squandered. Let’s squander some on Mars. Let’s go out and play.

Viagra does have a physiological effect, but it doesn't make women feel aroused. Nowadays, researchers are looking at drugs that affect the central nervous system rather than blood flow to the genitals.
