Can you imagine what's going to happen when they discover girls are NOT all 'sugar and spice and everything nice'? Next these devices will be in my toilet and I'll have to listen to announcements: "ALW we are concerned about all that wine you just drank....What vintage is it?? Stop drinking Italian and drink French" or " "That was not an 'organic' asparagus you just ate." One wonders what other diagnostics must be under investigation.

Cold virus detection from that guy who just sneezed next to you? A friend touches your arm and you find, ughhhh, her hand is loaded with germs?

It's not enough we have people getting run down by cars, drivers getting into accidents, and people falling off cliffs while texting? Add google type heads up displays.... and somebody thought electrical engineering employment might be waning.
