The Reality Check Episode 45

BMI + Michael Jackson Skin Colour + Eskimo(Inuit) Words for Snow

BMI Chart

 Part 1:

What is BMI?

It stands for body mass index, or Quetelet index, is a heuristic measure of body weight based on a person's weight and heigh. It does not really measure the percentage of body fat, it is used to estimate a healthy body weight based on a person's height, assuming and average body composition. Due to its ease of measurement and calculation, it is the most widely used diagnostic tool to identify weight problems within a population, usually whether individuals are underweight, overweight, or obese. It was invented between 1830 to 1850 by a Belgian polymath Adolphe Quetelet during the course of developing "social physics". The BMI is defined as the individual's body weight divided by the square of his or her height. It is used in kg/m^2. 

But this isn't really reliable, because a lot of other factors are essential as well, such as the person's age, frame, muscle density, and much more. Of course it's difficult to have to calculate everything, so it's just an easy way to see if you are okay. 

The big problem here is that if you use the BMI to calculate many great athletes, they would all be considered overweight or obese. 

Michael Jackson

Part 2:

Respect to Michael Jackson! Even if you don't like his type of music, you can't deny he's got loads of talent. 

It was back around 30 years ago, when Michael Jackson suddenly turned "white". Many people thought it was because he was ashamed of his ethnicity and color. But, from what Reality Check is saying, it seems like he said that it was because of some disease called vitiligo. Vitiligo is a chronic disorder that causes depigmentation of patches of skin. It's just the cells attacking each other when they are not suppose to. 

There's a way to not let people notice, it's to use makeup. We all know the Michael Jackson used a lot of makeup before. People said that it might the reason why he wears gloves all the time. 

Science Myth of the Week:

Do Inuits really have 400 words for snow?

This isn't true at all. They have around 30 words for snow, just as English does as well.
