I thought you might appreciate this vis-a-vis breasts and nipples. A month ago I was sent 4th generation thermal imaging monocular to try. Amazing. You can see human heat signatures through thin walls, or hand prints on walls, bare footprints on tiles, fifteen minutes after an unknown visitor leaves the room. Spent a few evenings on the beach testing the thing, hotel pools, too. Never saw so many flat-chested woman in my life. I mean completely flat. Weird until I finally realized why: silicon has no heat signature. That's right guys, if you want to find out who has real ones, or who's showing-off their implants, try thermal imaging. Feeling them is still the best way, of course, but thought you might like to know -- as fellow social scientists.
