One of the first things that we learn as a little kid is how to tie our shoes. It takes some children longer than others but eventually everyone gets it, usually when we decide that Velcro shoes are for nerds. One of the main reasons we learn to tie our shoes so fast is because we end up having to do it over and over again. No matter how hard we try, our shoes keep coming untied, (usually at the most inopportune moments). Terry Moore knows why, and he put on a TED talk to explain to us all how to fix this problem once and for all.
