This is the only article I’ve ever read that goes through those simple mechanics. Good work.

It should be noted that if you go around the loop twice before tucking, the lace will essentially never come undone on its own, yet is easily undone with a tug. I didn’t know about that until I was 45. Wish someone had told me. I still run across many grown adults who do not know this simple trick.

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
