Seriously, I just learned today from the linked website, and by noting the difference when I followed the instructions contained therein, that I have been tying my shoes incorrectly, using a weak slip knot rather than a stronger reef knot, for the last thirty years or so. Check out the site and let BP know if you have been tying your shoes correctly.
