Within reach

Any good workout routine involves stretching. The American Council on Exercise promotes three main reasons why:

1. It keeps you from being too sore. Stretching decreases muscle stiffness and helps improve your range of motion, which may slow the degeneration of joints.

2. It makes you stand taller. Stretching the muscles of the lower back, shoulders and chest will keep your back in better alignment and improve your posture.

3. It reduces stress. Well-stretched muscles hold less tension.

That math hurts my head!

Math anxiety has been a perceived phenomenon for years, but psychologists at the University of Chicago have recently proven that the fear isn’t only psychological; its physical, too. The research showed that the higher level of anxiety a person experienced leading up to a math task, the more brain activity increased in the areas related to visceral threat detection and pain perception.

Measles milestone

This year marks the 50th anniversary of the first measles vaccine to be licensed in the U.S. Prior to the introduction of the vaccine in 1963, there were an estimated 3-4 million cases of the measles every year. Today, the measles vaccine is a part of standard immunization schedules, with the first dose usually occurring between 12-15 months after birth. As a result, reported cases of the measles have dropped by 99 percent, with a total of 222 cases reported in 2011.

Disappearing bones

Most babies have 270 bones at birth, but fully grown adults have only 206. So what happens to the other 64 bones?Many bones in the skull and spine that are separate bones at birth fuse together over time to create a larger, stronger skeletal structure.

Taxing tax day

Money is the most frequently cited source of stress in Americans according to the American Psychological Association, with around 3 out of every 4 people citing money as a stressor in their lives. Given those numbers, it makes sense that Tax Day (April 15) is one of the most stressful days of the year, according to Gallup.
