From a recent article on the NYTimes
The aging effect is inevitable, and now runners can even track what to expect. It is as if there was a time clock for aging, and unlike nonrunners — who have only things like wrinkles and gray hair to go by — runners have an exact schedule that will predict how their performance will decline.
That schedule is on the website of Ray Fair, a professor in the economics department at Yale, who was inspired to find the patterns of slowdowns when his own running performance began to decline. The result is a table. You can put in your best time ever for an event, say a 10-kilometer race, and how old you were when you ran it. The table then shows how fast you could have run it when you were younger and how fast you should be able to run it now and as you grow even older.
And while this is very interesting, I do wonder about the rake implications and how I can determine bike handling characteristics based on it. I will ponder that and look for a mathematical answer, perhaps from differential geometry.
Mathematical Impressions: Bicycle Tracks
A nice mathematical puzzle, with a solution anyone can understand, is to determine the direction a bicycle went when you come upon its tracks. The answer involves thinking about tangent lines, geometric constraints and the bicycle’s steering mechanism.
The key to doing the 10000 steps a day is to be mindful of not running into people or behaving like an idiot.
I read this recent NYTimes article on the perils of distracted walkers and while I see the benefits of paying attention, I don’t really get the don’t-run-with-scissors-into-traffic list of absurd warnings at the bottom. I see too many folks navigate while talking on the phone using a headset to worry as much about them as I do about those who text, or who use their phone to count their steps. It reads a little like the UK IT police who warn us that kids who study computers beyond the curriculum at school have one of the top warning signs of cyber criminal activity (since withdrawn due to its stupidity, along with the warning about computer books, who are these people).
I do notice I stop when texting, although I wonder, is it to make sure I don’t run into others, or simply buildings or falling into an open manhole cover.
I like the idea of the 10,000 Steps A Day program, I was just wondering how I can track it easily.
I thought I would check Google Fit to see if it could help AND it was all there! From my phones. I had a lot of smaller activities that I shrank, but yesterday I did 4,817 steps. So I think I can boost this to 10,000 steps each day with just a little work and maybe a short walk.

How many steps do you walk each day?
Maybe you have heard the recent guidelines about walking 10,000 steps per day. How far is 10,000 steps anyway? The average person’s stride length is approximately 2.5 feet long. That means it takes just over 2,000 steps to walk one mile, and 10,000 steps is close to 5 miles.
Why it is so hard to find a great bike at a reasonable price? Brilliant Bicycle Company
Somewhere along the line, bicycles became complicated. Speed and spandex overshadowed the fun and prices skyrocketed. But bicycles shouldn’t be ridiculously expensive or intimidating, so we set out to build high-quality bikes for a fraction of the cost and to bring the magic and lightheartedness of your childhood back to bicycling.
