I would have recently agreed wholeheartedly with your ascertains. However, having recently witness my daughter suffer a violent allergic reaction accompanied by an expensive trip to the ER by doing something as innocuous as eating a cookie, I've had to shift my stance. In places such as daycare and primary schools where a child does not have enough faculty to understand that taking a bite of a friends lunch could kill them I'm all for peanut free zones. In settings where the child is old enough to know and to ask, It's a reasonable risk to allow. Until you've personally experienced a 3 year old son or daughter unable to breath and swelling up like a baloon, I doubt you can understand the "hysteria." So, for now, I'm sorry that your kids have to suffer such that my kid may live.

I'd imagine that it wouldn't be too difficult to use a wireless link from the camera to a battery powered dental retainer like receiver (think junior high and pimples). This way, the wearer, wouldn't draw unnecessary gawking. A few drawbacks, perhaps, would be that the tongue would need to be flush with the retainer on the roof of the mouth, so no talking whilst looking. Also, if you are running up a flight of stairs and need to draw breath through the mouth, it may impede vision. I am sure, a sighted person, could use this device to "see" light out of our normal range. What would it be like to see IR or UV?

I'm an epileptic you insensitive clod!

If habitable worlds, for life as we know it, are more common than once though in our own solar system, does this necessarily imply that other solar systems are more likely to contain such worlds? Or, perhaps, is our solar system somewhat unique in this aspect?

I used to have this problem, too, until I discovered that little white collar on the wire. When not in use, simply slide it all the way up. This prevents the majority of the knotting. Or, just get a pair that occupy 4 dimensional space -- that way it's impossible for them to get tangled up!

It certainly "feels" less responsive. Particularly when scrolling through a page then subsequently stopping and clicking a link, etc. A 3-5 second 'spinning ball of death' is not uncommon when traversing any given page.

Thanks for this comment. Obviously brilliant.

Not trying to sound like a fanboi... However, I have hundreds of data sheets for various microprocessors, IC's, power supplies, embedded API's, 5 years worth of emails, etc. Spotlight indexes them all beautifully, and access is very quick, only a few seconds to pull up all references. I believe spotlight will even index network attached storage although I could be wrong.
