The TED (Technology, Entertainment, Design) organization has produced some wonderful Talks since 2005. The very first Talk was by Terry Moore when he talked about how he found out that he had been tying his shoes the wrong way his whole life. Watch and enjoy the message:
This reminds me that it was my Grandfather PJ O'Loughlin who taught me how to tie my shoe laces. PJ died in 1965 (19th June), so I was very young (5) when he taught me how to do this. He taught me the "weak form" (as in the TED video). Like Terry Moore I had thought that by age 51 that I had mastered the art of tying my shoe laces - turns out that both my Grandfather and I were wrong! A "small advantage some place in life, can yield tremendous results some place else".
