I've just watched a 2005 video from TED which in just 3 minutes makes you realise how many things we take for granted. The video is by Terry Moore who explains that at age 50 he discovered there are two forms of the classic bow we use to tie shoelaces, the weak and the strong, and he had been using the weak form all his life - in the video he illustrates the difference.
What's more it turns out there are a lot more people out there who assume they know how to tie their shoes who are doing it wrongly. I checked and it seems I am doing it right, which I thought was cool, until a read an article that suggested that in many cases every other generation does it right, whilst the next does in wrongly, because we often learn the mirror form from our parents. So, although I may be doing it correctly, I may well have influenced my three children to use the weaker (the mirror) form of the knot.
Watch the video below, check your shoes, and then ponder about how many things we might be doing at work and in our wider lives which might be sub-optimal and might be equally easily fixed.
