To Medicate or Not to Medicate


When doctors prescribe medicines for pretty much every ailment, some people protest. Is it really necessary? Don’t the medicines have side-effects? Are the doctors getting a kickback for prescribing certain medicines? How will the immune system ever develop? Won’t germs become more resistant if we over-use such medicines?

On the other hand, doctors who recommend that the patient let the illness run its course are taking a chance. Will the patient just go to another doc who’ll prescribe medication? Will such a patient give a bad rating (online or verbally) about the doc to the clinic/ hospital/ friends?

I realized how complicated this whole topic can be as I read Nassim Nicholas Taleb’s Antifragile. Taleb mentioned that centuries back, a doctor, Ignaz Semmelweis, noticed that more women seemed to die giving birth in hospitals than giving birth on the street. His findings were dismissed, partly because the news didn’t suit the medical community; but also because he had no theory to explain this (germs had not been discovered back then; and hence the need for doctors and nurses to sterilize or wash hands was not a practice back then). Others wondered if it was just random: was the sample size large enough to warrant such a conclusion?

You’d think that in the West where healthcare is insured, insurance companies would prefer that doctors avoid medication unless really needed and thereby act as a counter-weight to the pharma industry that would push for more medication. And yes, that does happen to some extent.

On the other hand, governments often make certain vaccinations mandatory for kids in all schools. But why? Doesn’t that violate every question asked in the first paragraph of this blog? Paresh Talwalkar explains. He points out that kids who are vaccinated are immune; but additionally, by definition, they can’t spread the disease either; both of which are good things for everyone around. Now consider a parent who has heard of side-effects of the vaccine and is not keen to get his kid vaccinated. Further, he reasons: if everyone else gets the vaccination and my kid doesn’t, he’ll still probably be OK. This train of reasoning leads to the question:
“Why put your child through a vaccine shot if you don’t have to?”
But if too many people didn’t vaccinate their kids, then the risk of the disease spreading increase. Worse:
“This has a further effect of making the vaccine less effective–because even people who are vaccinated have a lower risk, but they can still catch the disease.”
And so game theory dictates that governments make such vaccinations mandatory!

To medicate or not to medicate: it’s not a simple topic, is it?

Student of the Year

Image
As a toddler, my daughter loved Alia Bhatt’s songs, esp. the ones from Student of the Year . (That movie did have many good songs and well-choreographed dances). Fast forward to present day, when she is 12 yo. She rarely watches Hindi movies now, but one of the few ones she likes of late, Raja aur Rani ki Prem Kahani has, yes, Alia Bhatt.   If I had any hopes that there was anything to be read in the name of her toddler-time favorite ( Student of the Year ), they have been dashed. Our conversations come exam time are perfectly captured by this photo and its caption: In fact, the pic below captures how she and I look at her answer sheets – me intently, she with an expression of “It’s over, so why are you even looking at it?”   Of late, we pull her leg and tell her that she isn’t showing any signs of academic prowess, she’d better find a rich guy to marry. Some time later, she showed us this meme on the Internet: “Me No Study, Me No Care Me Go Marry Millionaire If He Die

Animal Senses #7: Touch and Remote Touch

Instinctively, we think touch is based on contact. Not entirely true, explains Ed Yong in Immense World – there’s a more important aspect than contact: “These incredible feats are possible through movement. If you rest a fingertip upon a surface, you can get only a limited idea of its features. But as soon you’re allowed to move, everything changes. Hardness becomes apparent with a press. Textures resolve at a stroke.” As you run your fingers over a surface, they hit the tiny peaks and troughs and set off vibrations in the mechanoreceptors at their tips.   At the tip of its snout, the star-nosed mole has many pairs of hairless appendages. It uses them to touch things around itself. Alive or dead? Food or ignore? It does these movements at an insane speed. In the time it takes to blink our eyes, the star-nosed mole can probe, identify and swallow its food. “Light may be the fastest thing in the universe, but light sensors have their limits, and the star-nosed mole’s sense of

The Retort of the "Luxury Person"

Image
Coming up with biting and witty retorts. It’s something we dream of, but rarely manage to pull off. Worse, the more we stew over the offending remark, the more likely we are to come up with that dream retort, as Calvin ruefully points out: During our last holiday at the Taj Resort, seeing my wife carrying towels to our poolside chairs, one of the kids there mistook her for a member of the staff and asked for a towel. When my wife narrated this to us, I did not imagine that my 8 yo daughter would come up with her own retort. But a day later, my daughter recapped the incident, an incident that didn’t even involve her in the first place , and said, “You know what I’d have told that kid who asked for the towel?”. And without waiting for an answer, she told us anyway: “I don’t work here. I too am a luxury person who is living at this resort. Go get your own towel.” We were highly amused by the phrase she had coined: “luxury person”. It certainly captures the kind of holid
