A friend recently brought my attention to this link which contains 25 billboards by a Vancouver organization called Science World and I found the billboards to be insanely creative. So I figured I’d share some of them with you.
You can check out the rest of the billboards here.
And to make things a little more interesting, I’m going to explain the last billboard more. When you are scared, your body activates part of your autonomic nervous system called the sympathetic nervous system. This system is responsible for the three Fs (flee, fight and mate – you can substitute that last one with its F equivalent).
So the sympathetic nervous system prepares your body to either flee or fight in the same way. Part of this preparation is to cause pupil dilation in order to take in as much light as possible.
P.S.: you also see better when you’re aroused.
