Also known as "the bends" and Caisson Disease, decompression sickness affects divers or other people (such as miners) exposed to rapid changes in air pressure. In recent years, the medical term decompression illness has gained more traction—the term is technically more precise than decompression sickness, but it relates to the same condition.

As a child of the ’50s, I was a big fan of the hallmark TV series Sea Hunt and its indomitable hero, Mike Nelson, played by the late actor Lloyd Bridges. One episode I particularly remember involved the kidnapping of a scientist. As this was the era of Sputnik, it was implied — though never overtly stated — that the culprits were a group of “stinking commies.” The scientist was being held in a cave on an island. Central to the story line was the fact — seemingly unknown to the bad guys — that the cave could be entered from underwater. Of course, Mike Nelson knew all about the underwater entryway and planned a highly sophisticated escape: he swam into the cave, distracted the guards, gave the scientist a 30-second scuba lesson, dodged a few bullets on the way out and — fade to black — the world was once again a safe place for mom, apple pie and clean-cut capitalists.

The last thing you probably want to read is another tirade on the dangers of drinking and smoking. Besides, what can I say that’s new? Although some recent evidence points to drinking alcohol in moderation as a health benefit, no one doubts the dire consequences of imbibing in excess. And no informed person on Earth doubts that smoking is merely a form of protracted suicide. But while we’ve known about these dangers for decades, many of us still drink — at least occasionally — and a quarter of us smoke.

Food Sense for All Good nutrition is important to everyone’s health and can help prevent the onset of such diseases as Diabetes. For those who suffer with Diabetes or pre-diabetes, staying healthy is, in part, a matter of making the right choices when it comes to dietary intake. Sugars and other carbohydrates are readily converted to glucose, but the rate at which that occurs is measured by something called glycemic index. A high glycemic index indicates a food will rapidly be converted to glucose, causing a rapid spike in blood sugar. A low glycemic index means that the digestive process for that food is slower, meaning a slow production of glucose and a slower rise in blood sugar. For example, white rice rapidly converts to glucose and has a glycemic index of 72, whereas an apple, which converts much more slowly, has a glycemic index of only 36. However, the glycemic load, which includes the effect of typical portion size, may be an even better measure of a particular food’s effect on blood glucose.

We all know there are medical factors that can prevent people from diving. Epilepsy, various heart conditions, loss of consciousness, pneumothorax, some chronic diseases and even some forms of anxiety can spell trouble that may be incompatible with diving. But over the years, the list of contraindications has narrowed, allowing more to enjoy exploration of the underwater world.

In scuba diving, when it comes to assessing fitness, times have certainly changed. Years ago, many were reluctant to even consider diving because they thought it was deep, dark and dangerous. Today, it’s just the opposite. Many are lulled into diving because they view it as simple, safe and easy. Indeed, diving takes place in a relatively weightless environment, which may make it seem effortless, but it does require a degree of both health and stamina.
