1
the therapeutic value of amusement parks has been largely overlooked by doctors until just recently
2
that is with us in the studio today is Steven Mansfield
3
a medical journalist who is here to tell us about an amazing letter
4
that he read in the New England Journal of Medicine recently.
5
Stephen, welcome to the show.
6
Thanks for having me.
7
So, give us a bit of background on the letter you read.
8
I'd be happy to.
9
It was written by a Swiss eye surgeon named Michael Thiel.
10
It seems that a young man, 19 years old, presented himself to the doctor at his hospital in Zurich,
11
Switzerland, complaining that something strange had happened to the pupil of his right eye.
12
After being punched in the eye in a bar fight, the pupil, the black part at the center of the eye,
13
had become a long, narrow, vertical slit.
14
In fact, it bore an odd resemblance to the eye of a cat.
15
Thiel and his colleagues soon figured out what had happened.
16
Ten years before, it would seem, surgeons had removed the patient's natural lens and implanted a plastic one inside the eye.
17
The barroom punch had knocked the plastic lens out of place.
18
The lens had slipped forward, out through the pupil,
19
but the two tiny wires used to anchor the lens had remained in place farther back in the eye
20
and were tugging on the edges of the lens.
21
The backward pull distorted the pupil into a cat's eye shape.
22
So what did Dr. Thiel and his colleagues do next?
23
Well, first they tried a simple remedy, eye drops and gravity.
24
They had the man lie on his back and dilated his pupil with drops.
25
Their hope was that if the pupil opened wide enough, the lens would drop through it and wind up back where it belonged.
26
But according to Thiel, the procedure didn't do the trick.
27
Only half the lens went back, and the other part was stuck.
28
How awful!
29
Well, actually, it sounds worse than it was.
30
The patient's eye didn't hurt.
31
His vision was good, and he was in no danger.
32
But he wanted the lens fixed anyway.
33
His girlfriend and everyone complained that he looked funny.
34
And then what happened?
35
There he took three rides in a row on the Silver Star, one of the biggest, fastest roller coasters in Europe.
36
The ride climbs up an incline of 240 feet and zooms down into a curve at 80 miles an hour.
37
The force on passengers is four G's, four times that of gravity.
38
Apparently after the third ride the patient went to the men's room.
39
While washing his hands, he glanced at himself in the mirror and noticed that his eye looked normal.
40
The pupil was round again.
41
He called Dr. Thiel and explained what had happened.
42
The unbelieving surgeon examined him the following day and, to his amazement, found that the surgery was no longer needed.
43
The lens had slipped back into place.
44
How did he explain what happened?
45
The lens obviously needed quite some force to move it back into place.
46
When the patient was on the roller coaster, he was in a state of anxiety, combined with a lot of adrenaline.
47
Apparently, the adrenaline enlarged the pupil,
48
and it was probably the combination of this and the enormous g -force that brought the lens back into place.
49
Amazing.
50
So does Dr. Thiel and his team of Swiss surgeons recommend rollercoaster therapy to others with misplaced implants?
51
In fact, Thiel has realized that the story is actually a cautionary tale.
52
The obvious lesson to be learned here is that if a roller coaster can jolt an implanted lens back into place,
53
it may also be able to jerk one out of place.
54
Until recently, that might not have been so much of a concern, because most lens implants were used after cataract surgery on older people,
55
who probably did not ride roller coasters anyway.
56
But now, implants are being used in Europe to correct nearsightedness in younger people.
57
So even though riding a roller coaster was therapeutic in this case, the pastime may actually do more harm than good.
58
that's exactly right a dislocated lens can be more than a nuisance
59
if it slides far enough forward it may seriously injure the cornea well it's a good thing
60
that i'm afraid of roller coasters thanks for the fascinating report what was wrong with the young man's right eye
61
What was the first thing doctors tried to correct the problem?
62
How successful was their attempt?
63
In Dr. Thiel's opinion, what was it about the rollercoaster ride that corrected the problem?
64
What is the underlying message of the radio program?
65

¿Qué es la Técnica de Shadowing?
Shadowing es una técnica de aprendizaje de idiomas respaldada por la ciencia, desarrollada originalmente para la formación de intérpretes profesionales y popularizada por el políglota Dr. Alexander Arguelles. El método es simple pero poderoso: escuchas audio en inglés nativo y lo repites en voz alta de inmediato, como una sombra que sigue al hablante con solo 1-2 segundos de retraso. A diferencia de la escucha pasiva o los ejercicios de gramática, el shadowing obliga a tu cerebro y músculos de la boca a procesar y reproducir simultáneamente patrones de habla reales. Las investigaciones muestran que mejora significativamente la precisión de la pronunciación, la entonación, el ritmo, el habla conectada, la comprensión auditiva y la fluidez al hablar, convirtiéndola en una de las metodologías más efectivas para la preparación del IELTS Speaking y la comunicación en inglés en el mundo real.
