Why are Singaporean women so slim? Why do people feel so exhausted after a day of shopping?
These may seem like two unrelated observations, but Fresh Brainz has just discovered an interesting link between them!
Shopping is a form of exercise!
OK that isn't news. Walking directly to the store and back is a mild form of exercise, but you can't burn many calories that way.
However, that's not what people usually mean by "shopping".
I'll show you what I mean.
Here is a satellite photo of Orchard Road taken off Google Earth. I've used the "measure" tool to show you a hypothetical (but entirely possible!) path taken by a shopper as she starts her shopping adventure from the Orchard MRT station.
She checks out a bookstore and strolls through five shopping centres before taking a break at a cafe. Within this few-hundred-metre stretch of road, she has clocked an amazing 3.75 kilometres!
If you visit many stores during your shopping journey, you are actually walking a much longer distance than it first appears.
That somehow reminds me of fractals, and how Benoit Mandelbrot tried to measure the coastline of Britain with smaller and smaller rulers.
But that's too far off topic. Let's get back to our hardworking shopper.
You can estimate the calories she burned using an online calculator at this website.
For example, if she weighs 50 kg and took one hour to finish her shopping, then she burned 156 calories.
That's equivalent to jogging for 20 minutes.
Not bad at all.
In addition, if she bought a lot of stuff along the way, carrying all that additional weight helps to burn even more calories. So, the more you shop, the better the exercise!
Now I know why I haven't met a fat Tai-Tai.
