The predictability of our death rates is something that has long puzzled social scientists. After all, there is no natural reason why 2,500 people should accidentally shoot themselves each year or why 7,000 should drown or 55,000 die in their cars. No one establishes a quota (定额) for each type of death. It just happens that they follow a consistent pattern year after year.

A few years ago a Canadian psychologist named Gerald Wilde became interested in this phenomenon. He noticed that mortality rates for violent and accidental deaths throughout the Western world have remained strangely static throughout the whole of the century, despite all the technological advances and increases in safety standards that have happened in that time. Wilde developed an interesting theory called “risk homeostasis”. According to this theory, people naturally live with a certain level of risk. When something is made safer, people will get around the measure in some way to get back to the original level of danger. If, for instance, they are required to wear seat belts, they will feel safer and thus will drive a little faster and a little more recklessly, thereby statistically canceling out the benefits that the seat belt offers. Other studies have shown that where a crossing is made safer, the accident rate invariably falls there but rises elsewhere along the same stretch of road as if making up for the drop. It appears, then, that we have an inborn need for danger. In all events, it is becoming clearer and clearer to scientists that the factors influencing our lifespan are far more subtle and complex than had been previously thought. It now appears that if you wish to live a long life, it isn’t simply a matter of paying attention to certain precautions such as eating the right foods, not smoking, and driving with care. You must also have the right attitude. Scientists at the Duke University Medical Center made a 15-year study of 500 persons personalities and found, somewhat to their surprise, that people with a suspicious or mistrustful nature die prematurely far more often than people with a sunny disposition. Looking on the bright side, it seems, can add years to your life span.

As many as 4 out of every 1,000 infants born today have permanent hearing loss. When parents learn that their child has hearing loss, they are faced with many difficult decisions. These decisions can include choosing therapies and schools, as well as finding financial help for hearing aids or cochlear implants (人工耳蜗).

Help Me Hear Foundation is a public charity that gives the gift of hearing to deaf children from families existing on very low incomes around the world.

Help Me Hear Foundation believes that a child’s first years of development are critical. Being able to hear is vital to human, and Help Me Hear Foundation seeks to provide a positive lasting impression on society through its programs.

Recipients of Help Me Hear Foundation’s benefits receive state-of-the-art hearing devices that otherwise would cost thousands of dollars per child over the course of their lifetime. The Foundation raises money through donations for hearing aids and cochlear implants, which saves recipients and their families on average over $50,000 on related expenses.

The Foundation tries to be a transparent charity, and wants to be a catalyst for allowing deaf and hearing-impaired children to develop in a typical fashion alongside their peers.

Needy families can obtain information on specific services, and find out about deafness education by visiting the Help Me Hear Foundation’s website. The website offers helpful information on how hearing aids work, and how hearing aids ease many of the learning and language challenges that hearing-impaired children deal with on a daily basis.
