# How easy it is to take steps

Do you think taking steps is as easy as counting nuts? Try it, and you will see that getting to long names, you will not have time to mentally pronounce the numbers and start either to lose count, or involuntarily slow down the steps. How can you learn to easily take steps? This can be tried during a country walk, for example, on the highway, where, in addition, you can learn to measure the length of your step and the speed of walking. This will give you the opportunity to measure distances in steps. The main thing here is to learn a certain "measured" gait, that is, to train yourself to take steps always of the same length.

It is best to count the steps in pairs, so that the mentally pronounced numbers will always coincide with the exposure of the same foot, for example, the right one. In addition, if the hands are free, you can help yourself using the account on your fingers. The account of the pairs is only up to 10. When they count up to this number, the first finger is bent on the left hand; counting again to 10, the second finger is bent, etc. When all the fingers of this hand are bent, that is, after 50 pairs of steps, unbend all the fingers of the left hand and bend the first finger of the right. After the next ten, the first finger of the left hand is bent again, continuing to hold the right finger bent as a mark about the counted 50 pairs. After bending consecutively all the fingers of the left hand, then bend the second finger of the right hand and, releasing the left fingers, begin to use them again. Thus, using all the fingers of both hands, you can count up to 50*5 = 250 pairs, that is, up to 500 steps.

Then they start counting the steps again, as before, remembering that 500 steps have already been passed. Having practiced in such an account, you can learn to count the steps automatically, without being distracted from observing the surrounding. The result seems to be written down on your fingers: if at the last step we say "seven" and find ourselves bent with two fingers of the right hand and three left ones, then we are done:

2 * 50 + 3 * 10 + 7 = 137 pairs of steps,

that is, 274 individual steps (unless one of us has gone through one or more times of 500 steps before, that it is not difficult to remember).

It is easy to learn to count steps - this does not mean to determine the distance traveled. It is necessary to know the length of one step. There is one interesting relationship, discovered by multiple measurements: the average length of an adult's step is about half his height, counting to the eye level. But on occasion, you need to check this rule.

In addition to the length of your step, it is also useful to know the speed of your walking - the number of kilometers traveled per hour. Sometimes the following rule is used for this: we pass at an hour as many kilometers as we make steps in three seconds; for example, if in three seconds we make 4 steps, then in an hour we pass 4 kilometers. However, this rule is applicable only for a certain length of the step.

The speed of your walking can be measured in another way, by determining by the hour, how long you pass the distance between the two pillars.
