New Ways to Repel Sharks

Like South Africa, Australia is known as a region of frequent shark attacks. A lot of research has been done over the years in an attempt to reduce such attacks. Humans are not normal food for sharks. It is when humans behave in a similar way to injured fish that attacks occur.

Electronic pulses and sounds have been tried with limited success. Colored diving suits have also proven to be ineffective, until now. It has been discovered that blue lines on wetsuits disrupts the vision of sharks because they are color-blind.

White stripes also work as a deterrent but in a different way. Poisonous fish have white on their bodies. It tells potential predators that eating them will have dire consequences.

The cryptic wetsuit that "blinds" sharks is aimed at divers, while the white stripped warning suite is for those close to the beach. Diving equipment and surfing gear is also being colored to match the wetsuits.

Though shark attacks cannot be stopped entirely, the number of people injured is certain to fall. Tests at the Oceans Institute in Western Australia has shown that the new suits work very well. The new products will be sold by a company called Radiator.

Damage Claims for RSI and Internet Related Radiation Are Falling

Watch that computer. It could be bad for your health. Remember when complaints were rife about Wi-Fi signals damaging your brain? This charge was also aimed at mobile phones. Signals from towers were so small as to be hardly measurable. Radio and television transmissions are stronger. Home WiFi and computers generally are extremely low. 

You are more likely to suffer repetitive strain injury from using a computer than brain damage. Repetitive strain is becoming a problem in all industries because computer use is so widespread. The upper-limb and neck are the danger areas. Even now though, many "experts" say the "illness" is imagined.

It is difficult to prove that the injury was caused at work. People do many odd things away from work, though employment is the greatest culprit.  Like factory jobs where the same movements are repeated, data processors are likely to suffer from RSI. In the 1980s half of Telstra telephonists claimed they had RSI. Oddly, today few suffer from this, or fewer complain. Over time, the number of people off sick with this complaint has fallen despite computer use becoming more widespread.  It seems workers are putting up with the problem rather than being ridiculed.

Donkey Attack

People have much affection for the humble donkey. It is seen as being quiet and friendlier than the horse.  Donkeys do, however, kick and bite when they are made to do something they don't want to do, or are prodded and poked unnecessarily.

A Swedish lady kept a donkey with her horse. She thought it would make the horse happier and quieter. One day she separated the donkey from the horse. It became violent biting the lady's thumb. Furthermore, its teeth latched on firmly. She could not get it free the animal's mouth. Help arrived and a crowbar was used to pry the thumb away from the vicious bite.

The owner was taken to the nearest hospital and they found no breaks in her bones. She was bandaged, given a tetanus injection and taken home. A week late puss was oozing from the wound - she had not been given antibiotics. A sample taken from her hand showed the presence of Staphylococcus hyicus. This is common is the mouths of horses, but was not known to cause infection in humans.

The experience left the woman with a permanently numb area at the tip of her thumb. When you next feel like patting an animal that appears to be mild and friendly, just of think of the pain endured with the damaged thumb.

Blaming Rewiring of the Brain for Chronic Pain is Too Simplistic

What a cop out, medical "professionals" are now saying chronic pain is caused by a mixed-up brain. This cannot be the case when you have an open wound and it really hurts. They are saying we should not feel any pain at all. People with leprosy feel no pain and look what damage they do to themselves.

Pain is functional. It stops one using a limb when there is damage to it. Otherwise, it wouldn't heal properly. Most back pain is caused by damage to the spine that cannot be detected with current technology and knowledge.

Those "in the know" are now saying the brain rewires itself when there is an injury so that when the damage is repaired pain still continues. If this is the case then it is very selective. Why doesn't this happen when you cut your finger? We know if a limb is lost pain can continue, but saying the brain rewires itself after an injury is far too simplistic.
