Why are elections on Tuesdays? Until 1845 states set their own dates for federal elections

. Because that was chaotic, Congress picked a specific day of the week. Monday was out because many buggy-driving voters would have to leave home on Sunday. Wednesday was out because that was market day. Tuesday worked best in the 19th century. In the 21st century 15 states still require voters to go to the polls to vote. Supposedly, 25% of Americans don't go because they're too busy. It's been suggested more people would vote on a weekend, but that already lacks 1 vote - a vote of confidence.

What's the harshest sound in the world? In a study published in the journal Neuroscience, 13 volunteers listened to 74 sounds under an MRI machine, rating each one. The harshest sound was a knife against a glass bottle. Unpleasant noises increase blood flow in the brain's auditory cortex - where sound is processed - and trigger the amygdala - which processes emotions. The most disagreeable sounds had frequencies of 2,000-5,000 Hz, the part of the spectrum at which ears are most sensitive. The second harshest sound was a fork against glass. For the sake of peaceful meals perhaps this information should be "tabled".

Where's the safest seat in a plane crash? In 2012 a survivability expert from the National Transportation Safety Board headed a project that crashed a remote-controlled Boeing 727 loaded with sensors and crash dummies. Because the nose and cockpit buckled under the plane, the first 10 rows were destroyed. The area from the 11th row - but in front of the wing - showed serious, survivable injuries; and the area over the wing showed moderate, survivable injuries. However, people in the back of the plane would have been fine - if they were wearing seatbelts. Hmmm, first class doesn't sound so classy anymore.

Can you be scared to death? Yes, a shock can be sufficient to trigger a massive surge of adrenalin that stops your heart. Women - particularly postmenopausal women who no longer benefit from cardio-protective estrogen - account for 90% of cases. Stress cardiomyopathy is also known as "broken heart syndrome" because it often occurs after the death of a loved one. However, it can occur after a shock of good news too. As opposed to heart attacks, the hearts of cardiomyopathy victims can return to normal within a few weeks. It doesn't have to be a "heart-stopping" event.
