If you're interested in finding out about good or bad health habit travel, turning into Gadling this week would have been a good place to start.

• Anna tuned us into the countries where people smoke the most--if you value your lungs, perhaps you should rethink that trip to Greece, or at least avoid indoor eating establishments while you're there.
• Iva gave us a tip on how to not get sick after flying--can you say inhale? Plus, she gives the lowdown on the best sunblock formula.
• If you're wondering what eating goat meat morning noon and night might due to your digestive system, read Jerry's post on how time on the Galapagos almost did him in stomach-wise.
• Kelsey provides first hand know hows on how to protect yourself from food poisoning and
• Abha looks at the use of breathalysers in clubs as a way to prevent drunk driving.

Cash and Treasures, as mentioned in a previous post, is a Travel Channel show that often features kid friendly places. Host Kirsten Gum, an engaging sort, heads to where you can dig up treasure. I've been watching every Wednesday for the past several weeks, finding out more and more about the bounty one can find above and below ground. The finder gets to keep all of it for a price.

Episode: Digging for black opals

What are they? Stones of a variety of color ranging from black to blue with the shades in between that shine up into various patterns and designs. The design influences their value. Most of the opals in the world--95% come from this part of the world.

Location: Lightning Ridge, Australia--a small mining town that's a bit of a poke to get to. Gum said it took 11 hours through the Outback.

Digging details: Gum started her quest by heading to Black Opal Tours located in Lightening Ridge. This tour establishment is a place to find out about the various types of opal patterns and their value, as well as the history of opal mining in the area. While Gum was in Lightning Ridge, besides digging, she hob-nobbed with some of the miners and downed some beers, "stubbies," to find out about the miners experience and secrets. They kept the secrets to themselves. None of them looked like they are getting rich.

If you're looking for a cheap way to travel, and a cultural experience that will bring you past wandering in a country, hoping something significant in your life happens, here's an organization that looks like a promising possibility.

I read about it in a travel blurb and then headed to the Web site to check it out. Bridges for Education is a short term program where participants teach conversational English in exchange for cheap room and board and a week of cultural tours at the end of the teaching obligation.

The premise of the organization is that, by using teaching English as a tool, tolerance and understanding between cultures is fostered. Originally set up to answer the need for English language acquisition programs in Eastern Europe, the reach has expanded to Zhangzhou, China.

What would we do without The Economist and its great sidebars? This one shows just how much certain countries smoke. According to ERC, a market research company, the heaviest smokers come from Greece, with an average of 3,000 cigarettes per person in 2007. At 20 cigarettes per pack, that makes 150 packs in a year; a lot of puffing.

Despite recent smoking bans in many places, European countries still manage to hold 18 of the top 20 spots. The most surprising statistic? That France smokes less than the U.S. Whatever happened to the stereotypical image of the French, dressed in all black, a serious look on their face and a Gauloises glued to their fingers? It could have something to do with the price of cigarettes; a pack runs about 5 euros in France, equaling just a little under $8.

I'm struggling to make friends here. Miriam, a 9-month-old orangutan orphan who's learning how to climb a tree, almost scales past her trainer when I approach. For good measure, she starts to cry. Another orangutan signals displeasure by emulating the sound of a Harley barreling toward me. In fact, the only one who tolerates me is 11-year-old Leuser, and not because the 42 air-rifle pellets lodged in his body have mellowed him. He's also blind.

At any zoo, these surly apes would bomb the aw-isn't-he-cute exam, but here at the world's most successful school for rescued orangutans, they're taught to get back in touch with their wild side. Even playtime is serious business. Passing, say, the test of recognizing a friend (another orangutan) versus a foe (a human logger) could spell life or death for these critically endangered icons of the old world jungle.

Everything happens here with one goal in mind: graduation day, when the shaggy students are set loose into the harsh Sumatran rain forest. But for the students to have a shot at survival, handlers must teach them to avoid humans at all costs, a tough task considering they need to be fed by humans.

And teaching them about the dangers of Homo sapiens means no lines of gawky tourists dangling bananas and posing for pictures. That's why this center at the far north of Sumatra – one of the main islands of Indonesia – is closed to the public and barely known to outsiders. Even if you made it to the nearby village – where the specialty dish is fruit-bat soup and the humid air is clouded with mosquitoes - this part of Sumatra is definitely not for the faint of heart.

Whenever I hear about rich individuals owning whole islands, I always wonder how one actually goes about buying such a piece of property. Do you just walk into your real estate agent and say, "you know, I'm really in the mood for an island, do you have any available?" Seems like an odd question.

If you are in the market for your very own island -- and who wouldn't want one? -- the island of Hanö, off the Blekinge coast in the southeast of Sweden, is currently for sale. The idyllic island includes 6 kilometers of beach front and even a 19th century lighthouse. Although Hanö is protected under Natura 2000, an EU ecological network which protects the island and limits planning to the fishing village, whoever ends up buying the island will still obtain hunting rights to the many deer that wander it.

The island is being sold by the Swedish real estate firm Svensk Fastighetsförmedlingen, who is going so far as putting an ad for the island on national television station TV4. So how much does the island of Hanö actually cost? The real estate agency has not made a comment on the asking price, instead it will all depend on incoming bids, which need to be made by June 20th.

Even if you're not in the market for an island, Blekinge is still a beautiful part of southern Sweden that definitely merits a visit. Last summer I spent some time island hopping in the region that has a similar, but much more rural and laid-back, feel as Stockholm's archipelago. If your summer plans include a visit to Sweden, consider heading south for some traditional Swedish relaxing.

I heard that this weekend there are Civil War reenactors on the state house lawn in Columbus. This reminded me of my two friends who have dabbled in Civil War reenacting. Each dress up in period soldier attire-- one is in Confederate gray and the other is Union blue. As reenactors, they meet up other reenactors to act out a particular slice of history. There are rules involved for how reenactments are done.

It's not a matter of running around on a field any which way, but following the patterns and paths of what actually happened during particular battles during the Civil War. Clothing reenactors wear are to fit the time period and reenactors are often not supposed to take pictures. One of my friends said that he took a few pictures once when he was "killed" and down on the ground, but he had to be quick so people wouldn't notice.

The Web site Civil War Reenactment HQ lists several reenactment events and locations. Many reenactments include Civil War campsites and interpretive talks geared for various ages, parades and food.

One thing we've learned at Gadling this week is that oodles of people want those free Southwest Airlines tickets. So far, as of 3:44 pm, there are 1,162. Visiting people seems to be the biggest theme of many of the contenders' wishes.

Other numbers of note this week:

• Abha hooked us into a Web site that pairs 100 photos with 100 words in a single moment;
• Jeffrey noted that more than 600 people were rescued off a stranded ship in the Baltic Sea;
• In her world's most dangerous beaches post, Iva cited that in 2006, Americans took 55 million trips to a beach;
• Matthew clued us in on the 780,000 porno hits one man logged from his office in Japan; and
• Anna discovered that the world's longest bridge, located in China, is 22.4 miles long. If you drive across it too slowly, you'll get a fine. Since May 1, when it first opened, 300 people have had to pay up.

Share your numbers of note with us if you have any. One to think about is, how far can you get on one gallon of gas?

The last two weeks of The Travel Channel's Cash and Treasures on Wednesday night haven't included kids at the dig sites, a quality I was impressed by early on. Still, I continue to be hooked into this show. This week, I stuck around for the back to back episodes because host Kristin Gum headed out of the United States for points south in what worked as a double feature. Normally, the first half hour show satisfies me. The episode right after the first usually has a totally different theme.

Episodes: Digging for aquamarines, morganites and more.

What are they? Gems that can be worth beau coups bucks. Aquamarines range from dark green to a light blue, like clear water. Morganites are light pinkish. Gum found an aquamarine worth $3,000 and a morganite worth $1,481, once they were cut and polished.

Location: In the mountains and hills of Southeastern Brazil before the jaunt to Rio de Janeiro for the cutting and polishing. The first episode was shot in Governardor Valadares in the state of Minas Gerais at the Jaco Mine. The second episode was at the Rio Doce Mine near Rio Doce.

Getting to the Jaco Mine involved first taking a train and then a jeep on an unpaved road with 32 switchbacks. The bonus of the effort, besides the gems, was the gorgeous scenery. Gum was given mining tips by the mine's owner and his son. The snaking tunnel of the mines where the walls shimmered turned up nothing, but once Gum sifted through the tailings using a large screen, she found several aquamarines. One of them was large piece that was turned into the $3,000 beauty. The others were the type you'd put in a collection and were not considered valuable.

Traveling allows us to experience many new things: unique cultures, languages, food and wildlife. I am always up to experience it all but it's the creepy crawlies that fall under the "wildlife" category that I'd prefer not to encounter--no matter how hard I try to avoid bugs they somehow always know where to find me.

The other night, just before I was about to hop into bed, I happened to notice something move on the floor below the bathroom sink. My first instinct was SPIDER! and I quickly told Tom, my resident bug catcher, that he might have some work to do. On closer inspection I realized that it wasn't a spider it was instead a rather cranky looking SCORPION! Needless to say that got the bug-catcher moving. We (he) caught it, let it go outside and then each of us performed a fantastic bug dance.

You won't just find beaches in Baja Mexico but an arid desert as well. And this desert is home to a few creatures we'd all like to avoid. Here are a few critters to watch out for in Baja California Sur, how to minimize any encounters and what to do if things get "a little too close for comfort."
