interestingly it looks like a subject could wear it all day while doing normal stuff

"I got my hands on an early version of Interaxon's brainwave reading headband, the Muse, and I think this could be the most important wearable of the year. And that's saying a lot, considering I've seen 2014′s entire lineup for health tech at the Consumer Electronic Show as well as a few undisclosed athletic devices slated for later this year."
..."alerts the users with sights and sounds when they are producing brain waves associated with calm and focus."
ALERT! ALERT! ALERT! YOU ARE CALM AND FOCUSSED!
:-D
one of these again. french illustrations from 1910 of life in the year 2000. some pleasingly close. a lot of flying and robots. some inexplicable (bunch of people staring at a horse). some bmi.
Ha! The one about the horse is that "in 100 years there will be people who've never seen a live horse in their lives" :-) Actually it's more than true now with children asking my mother who works in the school "so, do those kangaroos really exist"? Children are fed with so much realistic BS on TV (dinosaur parks etc.) that they can hardly tell the difference between fiction and reality. If you already have offspring: have they seen, say, a live cow or chicken already?
(This is most probably a reference to the quote: "Horse is as everyone can see")
