“With all the fuss over TED’s self-censorship, we searched through hours of footage to find 10 talks the organizers really should have excised” writes Foreign Policy associate editor Joshua Keating.

Why? Just so that Foreign Policy readers could waste their time watching TED talks that in Keating’s view aren’t worth watching?

Curious to find out whether I happened to have already made the mistake of watching one of these scrappable talks I browsed the list. I had indeed watched the second one: Terry Moore’s presentation on how to tie your shoes.

Maybe Keating only wears loafers or maybe he happened to learn the strong knot when he first learned to tie laces, but for anyone like Moore or me who has gone fifty or more years with shoes laces that with irritating frequency have habit of coming loose, this lesson in shoe lace tying is of immense value. It also demonstrates how easy it is to move through life thinking you know something only to discover you were ignorant.
