Natural light need not be so frightening. We can experience it indoors before moving to the more challenging outdoors. Thankfully, some clever soul realized that fluorescent light is not good for humans, and tends to drive them insane and hate people in
cubicles. This person invented "full-spectrum" lights which give off light very similar to that produced by the immense
ball of fire.
Some companies have been nice enough to install this lighting already. You may notice that the light appears more
pink than standard
fluorescent. You may also notice that your
mood is lifted a small bit. Now, if you can sit in this light for a while, then you are probably ready to go outside to the
natural light. Just remember, the natural light outside is much, much brighter (unless you live in Cleveland) and you'll probably need some sunglasses and sunscreen.
Good Luck!
