Actually, you're trusting Google that that's how the ad generation is done, that no human eye, no Gmail Man eye, ever lays on anyone's email. I don't trust Google that much.
How many billions of pieces of email does google move in a day? I doubt that they're looking at my emails with eyeballs. Are they "reading" it and picking out keywords to send me an ad, oh, of course, yes. But I don't care.
