I find the things we don’t really know fascinating. It turns out that scientists don’t really understand why we blink so often. The eyeball lubrication and cleaning is seemingly obvious — and those claims are not being refuted. But it appears we blink far more often than cleaning and oiling our ocular orbs requires.
Today smithsonian.com wrote a bit about a study released today that investigated the possibility that we blink for cognitive reasons. Apparently it is common for people watching the same video to even blink at roughly the same times.
Very interesting stuff. It’s not definitive, but it sure is fun to learn more about the things “right in front of our faces” that we still don’t understand. Awesome.
