The Elusive Nature of Medical & Other Truths - Part 1

Recently, the practice of "aesthetic medicine" in Singapore received a lot of media attention. Since I like my own face as it is, I did not really pay much attention to the specifics of the debate.

However, I did gather that some doctors in Singapore have been offering beauty treatments which are "scientifically unsubstantiated". The issue is whether these doctors should be stopped, and if so, how.

For more background, refer to these doctors' blogs - Angry Doctor; Alien Doc; and No Fear Singapore. (Notice how doctors tend to choose such unusual blogging names for themselves).

Health Minister Khaw Boon Wan has taken the position that the Ministry will step in only as far as invasive, high-risk procedures are concerned.

Thus the Ministry will not bother to intervene with non-risky beauty treatments, even if their benefits are not scientifically proven. Instead the Ministry will leave it to the medical profession to regulate itself on such matters, through organisations such as the Academy of Medicine.

In my opinion (although Angry Doctor would furiously disagree), Khaw's approach is very sensible.

I am quite confident that most, if not all, the aesthetic treatments offered by your neighbourhood HDB beautician are also "scientifically unsubstantiated". This does not mean that all these aesthetic treatments do not work.

It merely means that the treatment either does not work, or the treatment works, but has not been "scientifically" proven to work. And most of the time, the latter simply means that scientists have not bothered to do research on that particular treatment.

Which is quite alright, if the treatment does not harm or hurt you. It just means that you may have wasted some of your money on your neighbourhood HDB beautician. Your loss. Next time, try some other fruit or vegetable.

"Mr Wang is wrong. Chillis would hurt.
And durians could be downright dangerous."


Now the question then is whether we should regard doctors who provide aesthetic treatments in the same light as neighbourhood HDB beauticians.

Obviously there is some risk to the reputation of the medical profession, if many doctors go around offering beauty treatments which are non-risky but scientifically unsubstantiated to be beneficial.

The reputational risk to the medical profession would decrease, if these doctors offer beauty treatments which are non-risky and scientifically unsubstantiated, and actually work. (Happy patients don't file complaints).

But either way, the potential damage is only to (1) the medical profession's reputation, and (2) the patient's purse.

If you're not a doctor, well, frankly, who cares about Risk (1). And if you're the patient, well, Risk (2) is no different from the kind of risk you face, going to any beauty salon or parlour.

So I think Khaw is quite wise to leave it to the medical profession to regulate itself.

Thoughts Affect Reality. Let's Imagine Muscles

Hilariously, some readers are still missing the point. I wonder when they'll get it.

I have been using different sorts of examples to illustrate the "thoughts affect reality" concept.

But when I used Buddhism as an example, some readers said I shouldn't use Buddhism.

When I used quantum physics, some readers said I shouldn't use quantum physics.

When I used financial markets, some readers said I shouldn't use financial markets.

When I used rats and children in the Rosenthal experiment, some readers said I shouldn't use rats and children.

They miss the point. They just don't see that reality refuses to be divided up into neat slices according to our academic classifications.

Reality is not "Buddhism". Reality is not "quantum physics". Reality is not "financial markets" and reality is not "rats" or "children".

Reality is just reality. And thoughts affect reality - all of it. Whatever you think about.

And that is why you can look into ANY area of reality, including such diverse areas as Buddhism, quantum physics, finance, psychology etc, and still find evidence of the same "thoughts affect reality" phenomenon at work.

Today, what shall we talk about? Ummm, let's see. How about health and fitness? Shall we proceed to grow our muscles just by thinking about them?

"Ridiculous! Mr Wang is insane! Next he'll tell us that scientists have really discovered that you can increase your muscle size AND strength, just by thinking!"

Yawn. It's quite old news, actually:
Physical Training in Your Dreams

Scientists have come up with just about the best news that a couch potato could ever want to hear.

They say you can increase the strength of your muscles just by sitting back and imagine yourself taking exercise.

The discovery could help patients too weak to exercise to start recuperating from strokes or other injuries.

If the technique works in older people, they might use it to help maintain their strength.

Muscles move in response to impulses from nearby nerve cells called motor neurons. The firing of those neurons in turn depends on the strength of electrical impulses sent by the brain.

Dr Guang Yue, an exercise physiologist at the Cleveland Clinic Foundation in Ohio, says that this suggests you can increase muscle strength solely by sending a larger signal to motor neurons from the brain.

New Scientist magazine reports that Dr Yue and his colleagues have already found that visualising exercise was enough to increase strength in a muscle in the little finger, which it uses to move sideways.

Flexing biceps

Now his team have turned their attention to a larger, more frequently used muscle, the bicep.

They asked 10 volunteers aged 20 to 35 to imagine flexing one of their biceps as hard as possible in training sessions five times a week.

The researchers recorded the electrical brain activity during the sessions.

To ensure the volunteers weren't unintentionally tensing, they also monitored electrical impulses at the motor neurons of their arm muscles.

Every two weeks, they measured the strength of the volunteers' muscles.

The volunteers who thought about exercise showed a 13.5% increase in strength after a few weeks, and maintained that gain for three months after the training stopped.

Controls who missed out on the mental workout showed no improvement in strength.

The researchers are now repeating the experiment with people aged 65 to 80 to see if mental gymnastics also works for them .....
Boy, this sure gets repetitive. Do I have to say it again? Thoughts affect reality, yadayadayada.
