One of the risks of being a writer is a tendency to fall into sedentarianism (which isn’t a word, but ought to be; clearly, it refers to a religious belief that the best way to avoid sin is to do as little as possible).
Aside from those keeners who have set up combination desks/treadmills (Arthur Slade, I’m looking at you), a poor choice for those of us who cannot walk and chew gum at the same time, much less walk and type at the same time, most writers do little but sit on their rear ends and tap on a keyboard.
It was therefore with great interest that I read a ...

Exercise is good for you. It’s a shame, since I personally find the whole sweating/breathing hard/ hurting thing a (literal) pain, but I don’t believe I can mount a successful argument as to why sitting on your rear end eating junk food all day is actually better for you, even though evolution seems to have inclined us to do it.
(It’s interesting to note that “survival of the fittest” is only one letter away from “survival of the fattest,” and one reason we’re so fond of high-calorie foods is that when food is in short supply, it really is the fattest who are the fittest to survive. But I digress.)
I’m not ...

There’s a perception that science is always reversing itself. If you don’t like what science has to say about, say, the health benefits or risks of a particular food (eggs, for example, or coffee), you only have to wait awhile until a contradictory study comes out.
That’s because science progresses in fits and starts. Researchers put forward a possible explanation, a hypothesis, for the results of an experiment. Other researchers attempt to duplicate their results and refine the hypothesis. Sometimes the hypothesis is completely discarded, and a new hypothesis gains sway.
But in the media, this slow process is seldom reported. It’s much easier to pick up on the report of a single study—particularly if it has startling results—and present the hypotheses ...

It's summertime in Saskatchewan, and that means the roads are full of joggers, walkers--and bicyclists.
The first bicycle was the "celerifere," or wooden horse, invented in France in the 1790s. It had a fixed front wheel, so it couldn't be steered, and the rider propelled it by pushing his feet along the ground, like Fred Flintstone.
A German baron, Karl von Drais, added a steerable front wheel in 1817, creating the "draisienne," or dandy horse. In 1839, Kirkpatrick Macmillan, a Scottish blacksmith, added pedals which drove the rear wheel by means of cranks.
In the 1860s the French invented the velocipede, on which the pedals were attached directly to the front wheel, so that once ...

I wouldn't call myself a "serious" cyclist, since I don't wear neon Spandex shorts and top, a colour-coordinated helmet, leather gloves or fancy cycling shoes. Heck, I don't even have a water-bottle. But I do cycle a bit, and as I was puffing my way along the bike path the other day it seemed to me the time was ripe to write about the science of cycling. (Besides, I'm a sucker for alliteration.)

I hate exercise. It's uncomfortable, sweaty, and cuts into quality TV time.
Unfortunately, it's good for you.
Exercise is physical exertion for the purpose of improving physical fitness. (If it's for any other purpose, we call it "hard work.") Modern fitness programs got their start in Prussia in the 1800s (which should tell you something). Feminists took up the idea to prove that women are not frail, and in fact the word "calisthenics" was coined in 1831 by the headmistress of an American girls' school, from the Greek words kalos, "beautiful," and shenos, "strong."
The primary component of all exercise, from jogging to marathon ballroom dancing, is ...
