When I attended that talk about creativity as part of the World Science Festival several weeks ago, I arrived at the lecture theatre quite early (as I do). As I sat and waited for the talk to begin, I watched the slide show of random interesting facts that they had playing. One of these facts was about how we blink so often, that we spend about 10% of our time awake with our eyes closed.
Since then, I’ve thought intermittently about this – perhaps while sitting at a computer, thinking that we blink less while staring at screens of some sort; or perhaps while out and about in the world, and wondering about all the details that I’m missing by inadvertently having my eyes closed 10% of the time – but I always reasoned that it couldn’t be that significant a loss, since it’s not like we have our eyes closed for entire blocks at a time (say, for example, 6 minutes at the start of every hour) and then keep our eyes open the rest of the time. And because blinking takes next to no time at all, and it’s so spread out, we’re not really losing anything in our experience of the world, right?
