Vision Optic Co. in Japan has created glasses that stop people from falling asleep.

When I was growing up the television closed down – literally – at midnight and there wasn’t much chance of going shopping or paying a few bills at midnight because all the shops firmly shut at 5.30pm. Convenience stores and online banking had yet to be invented. But it’s not just that we need more sleep to incubate ideas, we need to daydream more too. An article in the Boston Globe claims, when we daydream, a specific pattern of brain activity is activated. This is known as the default network and it is in this brain state that the mind starts to make connections between seemingly unrelated information, ideas or events.
