Ideas and ties


By the way, a few days ago this news appeared in the media:

"Scientists reveal the negative effects that wearing a tie can cause in the brain.

A group of German scientists revealed that tight ties reduce the flow of blood to the brain by crushing the neck veins. The results of the study were published in the Neuroradiology. Robin Lüddecke, of the University Hospital of Schleswig-Holstein, Germany, and his colleagues scanned the brains of 15 healthy young men before and after putting on a tie.

Each participant was instructed to tie a Windsor knot and tighten it to the point of slight discomfort. Right after the men narrowed the ties, the blood flow in their brains fell by an average of 7.5%. No changes in blood flow were observed when the experiment was repeated with 15 men who did not put on a tie.

The scientists found that the use of a loop compresses the veins in the neck, pushing the blood into the skull and creating a build up of pressure. It is very likely that this additional pressure will crush the blood vessels of the brain and reduce blood flow, says Lüddecke."

That explains a few things...
