Have you actually watched TSA at an airport? As one of the
"statistically insignificant" 40-something, balding, middle-aged white
guys, my statistical insignificance has achieved an 80% secondary

nothing in my profile that should trigger such a high amount of screening
for a truly "random" process.

Maybe they've been reading your posts on this newsgroup (he says, running
and ducking for cover).
