The $97 shirt revisited …

Let’s revisit the problem …

You saw a shirt for $97.

Having no cash, you borrowed $50 from your mum and $50 from your dad.

$50 + $50 = $100.

You bought the shirt, and had $3 change.

You gave your dad $1 and your mum $1. You have a dollar in your pocket.

You now owe your mum $49 and your dad $49.

$49 + $49 = $98. Add the $1 you still have = $99.

Where is the missing dollar?

This is apparently hurtling around the internet to the puzzlement of many in their late teens to early twenties.

The first point to be made is that if you have no money, what you need from your shirt is that it make a good impression at your next job interview … $25 at target.

Secondly, if you have $3 in your pocket, no matter how it came to be there, and you give $1 to your Mum and $1 to your Dad you will have $1 left … the world does not owe you an extra dollar.

So let’s take it from the beginning …

You borrow $50 each from Mum and Dad. You have $100 in your hand.

You spend a ridiculous amount on a shirt and now you have a shirt in one hand and $3 in the other.

You give two dollars away, you are left with $1, a shirt and, because you reduced your $100 debt by $2, a debt of $98 … what else did you expect?

The puzzle evaporates in the face of logic but on first reading it has a certain pull … because it invites you to do a sum that simply isn’t itself logical and leads to a wrong answer.

If you saw straight through the puzzle congratulations.

If you didn’t you may need to temper your expectations at the job interview.

If you wrote the puzzle there’s a guy in Canberra named Wayne Swan who needs a hand finding a few missing dollars.

Dummies’ guide to what went wrong in Europe.

Helga is the proprietor of a bar. She realizes that virtually all her customers are unemployed alcoholics and, as such, can no longer afford to patronize her bar. To solve this problem she comes up with a new marketing plan that allows her customers to drink now, but pay later.

Helga keeps track, in a ledger, of the drinks consumed (thereby granting loans to the customers).

Word gets around about Helga’s “drink now, pay later” marketing strategy and, as a result, increasing numbers of customers flood into Helga’s bar. Soon she has the largest sales volume for any bar in town.

By providing her customers freedom from immediate payment demands Helga gets no resistance when, at regular intervals, she substantially increases her prices for wine and beer – the most consumed beverages.

Consequently, Helga’s gross sales volumes and paper profits increase massively. A young and dynamic vice-president at the local bank recognises that these customer debts constitute valuable future assets and increases Helga’s borrowing limit. He sees no reason for any undue concern, since he has the debts of the unemployed alcoholics as collateral.

He is rewarded with a six figure bonus.

At the bank’s corporate headquarters, expert traders figure a way to make huge commissions, and transform these customer loans into DRINKBONDS. These “securities” are then bundled and traded on international securities markets.

Naive investors don’t really understand that the securities being sold to them as “AA Secured Bonds” are really debts of unemployed alcoholics. Nevertheless, the bond prices continuously climb and the securities soon become the hottest-selling items for some of the nation’s leading brokerage houses.

The traders all receive a six figure bonus.

One day, even though the bond prices are still climbing, a risk manager at the original local bank decides that the time has come to demand payment on the debts incurred by the drinkers at Helga’s bar. He so informs Helga. Helga then demands payment from her alcoholic patrons but, being unemployed alcoholics, they cannot pay back their drinking debts. Since Helga cannot fulfil her loan obligations she is forced into bankruptcy. The bar closes and Helga’s 11 employees lose their jobs.

Overnight, DRINKBOND prices drop by 90%. The collapsed bond asset value destroys the bank’s liquidity and prevents it from issuing new loans, thus freezing credit and economic activity in the community.

The suppliers of Helga’s bar had granted her generous payment extensions and had invested their firms’ pension funds in the BOND securities. They find they are now faced with having to write off her bad debt, losing over 90% of the presumed value of the bonds. Her wine supplier also claims bankruptcy, closing the doors on a family business that had endured for three generations.Her beer supplier is taken over by a competitor, who immediately closes the local plant and lays off 150 workers.

Fortunately though, the bank, the brokerage houses and their respective executives are saved and bailed out by a multibillion dollar ”no-strings-attached” cash infusion from the government.

They all receive a six figure bonus.

The funds required for this bailout are obtained by new taxes levied on employed, middle-class, non-drinkers who’ve never been in Helga’s bar.
Now do you understand?

Parque Nacional da Serra da Canastra …

Twelve hours on the road will get you across the state of Minas Gerais from Caratinga to São Roque de Minas, site of the closest hotel to the Canastra National Park.

The great attraction of this part of Brazil is the Giant Anteater, not easy to find anywhere this is where your chances are best. The park opens at 8 am … unless of course it’s on fire.

A major grass fire was ripping through the park, it was closed for the two days we were in the neighbourhood. Not an unfamiliar situation for an Australian.

There is a stream at the foot of the range with some remnant forest and not too far away the private Reserva Natural da Cachoera do Cerradão. The birdlife is prolific and colourful. Another primate graced us with fair views, the Maked Titi Monkey.

The contest for the most beautiful bird in Brazil would be a very difficult one to judge but at the Reserva we saw both the Pin-tailed and Helmeted Manakins, both would be in with a chance.

And wandering across the countryside a distant Giant Anteater …

 

Freedom to abuse …

Alan Jones has shot himself in the foot and the ricochet has hurt the cause that he holds dear. What a noodle.

That the prime minister is a liar is news to no one, to bring her father into the debate is pointless.  The pain of losing a loved parent is great, to trespass upon that loss is insensitive, ill-considered, bad manners and really bad strategy. I’m sure Mr Jones regrets his utterance. That he tries to shift the blame to those who recorded and disseminated his words just makes him look weaker. He is not the first person to blame others for his own stupidity, I’m sure he’ll get all the sympathy he deserves for that.

Trust the government, though, to call for his punishment, to use this issue as another excuse to attack freedom of speech.

The freedom to say only what the government wants to hear is no freedom at all.

And this would appear to be a very good case for letting free speech have its head. Intemperate and ill-considered speech rebounds on the speaker.

Shirts, $97 …

You saw a shirt for $97.

Having no cash, you borrowed $50 from your mum and $50 from your dad.

$50 + $50 = $100.

You bought the shirt, and had $3 change.

You gave your dad $1 and your mum $1. You have a dollar in your pocket.

You now owe your mum $49 and your dad $49.

$49 + $49 = $98. Add the $1 you still have = $99.

Where is the missing dollar?

Muriqui …

Next stop on the Brazil foray was Caratinga, specifically to see the Northern Muriqui.

These are the largest South American (non-human) primates. There are fewer than 1000, they are restricted to the Atlantic Forest region of Brazil and because of fragmentation of the forests the remaining Muriqui are languishing in small isolated groups. The best studied group are to be found on a private reserve – Reserva Particular do Patrimônio Natural Feliciano Miguel Abdala, in the state of Minas Gerais. All praise to its owner.

The Muriqui has long limbs and a long prehensile tail. They swing through the trees with great agility eating mainly young leaves and fruit They live mixed-sex groups of between 8 and 80 individual which are not particularly territorial or aggressive. Females tend to give birth to a single offspring during the May – September dry season. Male offspring remain with their natal group. Females disperse to join other groups once they have reached adolescence at 5 – 7 years.

We found a female with a baby and an older sibling almost immediately and later a group of twenty or so.

We spent a long time with the Muriqui, but as is always the case, time in the field is always rewarded. The day yielded 44 species of bird and three more primates … Buffy-headed Marmoset, Brown Howler and Black Capuchin. Plus a Nine-banded Armadillo made a brief appearance, it’s rare to see these at all and most sightings are at night.

And the wildlife …

… treated me very kindly.

The South American Coati, Nasua nasua, is quite common at Iguaçu. It is a member of the raccoon family (Procyonidae). They are about 30 cm tall at the shoulder, and weigh between 2 and 8 kg. Males are much bigger than females and once mature live a solitary life except in the mating season. Females and young tend to travel in bands with their tails raised. They are equipped with powerful claws and sharp teeth, the long tail is not prehensile. Their snout is capable of quite a range of movement.

 

The Black Capuchin is less intrusive in its habits. It is a primate, of course.

One of the rarest and most spectacular birds that I saw on the trip was the Black-fronted Piping-Guan, Aburria jacutinga, crippling views …

 

Cataratas del Iguazú …

Argentinians speak Spanish with a marked accent. I studied Spanish with a teacher of Argentine origin. Some years ago I met some tourists from Barcelona who thought my Spanish was so awful because I was Argentinian. On my recent day trip to Argentina I met some locals who thought my Spanish was so awful because I was Brazilian. There is a consensus on my Spanish.

The trip from Iguaçu to Iguazú was relatively painless, recent changes mean that there are no formalities at the Brazilian border post but there is still a delay on the Argentinian side. The journey takes you in sight of the confluence of the Iguazu river with the Paraná. You can see Argentina on one side, Brazil on the other and Paraguay in between. Poor Paraguay, history has not been kind to her.

From the car park it’s a short walk and a train ride out towards the falls. From the end of the line there are a number of paths that lead to spectacular views. The most spectacular of all is to a platform on the very tonsil of the Devil’s Throat, la Garganta del Diablo. If you want a photo from here take a waterproof camera and a very wide-angle lens. Here you are conscious of the sheer power of the falls.

Other walks trade power for panorama.

It’s easy to see why Eleanor Roosevelt on seeing Iguazu  exclaimed “Poor Niagara!”

Cataratas do Iguaçu …

The Iguaçu river arises on the inland side of the Brazilian coastal range. Water that falls on the other side of the watershed doesn’t have far to travel to the sea, but the Iguaçu heads west through Paraná State, becomes the border between Brazil and Argentina and after 1,320 km it empties into the Paraná River at the point where the borders of Argentina, Brazil, and Paraguay meet, the Triple Frontier. The Paraná goes on to collect the Paraguay River and later the Uruguay River forming the Río de la Plata which empties into the Atlantic Ocean at Buenos Aires. It is the second longest river system in South America.

Not far from the Triple Frontier the Iguaçu drops with spectacular force over the edge of the Paraná Plateau.

The edge of the falls is 2.7 km long and the flow is interrupted by islands. The most spectacular point is the Devil’s Throat (since I am standing on the Brazilian side, the Garganta do Diabo).This is a long and narrow chasm 82 meters high, 150 m wide, and 700 m long. It collects about half of the river’s flow.

The area surrounding the falls is protected by national park on both the Brazilian and Argentine side. There is a gorgeous old hotel on the Brazilian side …

Turning right about 120 degrees gives a view of the falls …

Walkways from the hotel take you down hill slowly to the foot of the falls. An elevator! will take you up to a car park to catch a bus back if you want. For those with more vigour it’s not that arduous a walk back.

The forest around the falls is rich in wildlife. We encountered Coatis, Black Capuchin monkeys and Azara’s Agouti. Don’t feed the wildlife – remember Brazil does have rabies although Amazon bats and urban dogs are the main vectors. The bird list grew rapidly and included Red-rumped Cacique, Surucua Trogon, Toco Toucan, Plush-crested Jay and Chestnut-eared Aracari just to mention the more spectacular. And the butterflies were doing their best to rival the birds.

Great Dusky Swifts congregate in immense numbers above the falls and roost behind the curtains of water.

 

There is no one spot that permits a view of all the falls. The experience has to be put together in increments. To see the falls from one side only would be to sell yourself short, so tomorrow it’s off to Argentina.
