Then you stumble into the kitchen and accidentally eat that entire pie your spouse was saving. So annoying!
There's a much better way to get around at night than winging it, though. This is going to sound like we're trying to trick you into walking into a wall, but we swear it's true: Simply don't look where you're going. Point your eyes elsewhere, and let those usually murky images on the periphery of your vision guide you.
How the hell does that work? Well, human vision relies chiefly upon the combined effort of two types of light-sensitive cells in the retina: cones and rods. The six to seven million cones in your eye are awesome at detecting colors and finer details, while the 120 million or so rods ... aren't. However, to compensate for getting shortchanged on the "resolution" and "ability to discern color" fronts, the rods have night vision and ultra-sensitive motion detection. There are millions of tiny Daredevils living in your eyes, basically. More specifically, around the sides:
We also have several Hulks, apparently.
Cones mainly populate the middle area of your vision to offer the best resolution of whatever you're staring at, while rods are concentrated in the peripheral areas. Therefore, by not looking where you're going in the dark, you activate your body's natural night vision and rough shape-detection capabilities, allowing ninja-like evasive skills as you glide between coffee tables and litter boxes with nary a stubbed toe on your way to the toilet.
