Anyways, that is that. The term I want to dwell on somewhat is “tail wind”, i.e. wind that blows from behind you. This is originally a shipping industry term. In the old days, when ships didn’t have such strong propellers as are seen today, anyone could use a little tail wind. In other words, sailors all loved to have the wind blowing from behind the ship, thus pushing the ship forward.
Tail wind, hence, came to stand for any extra help or outside influence that contributes to one’s cause. Tail, as in the tail of a dog, which is behind the dog, as opposite to the head which is in the front. Head wind, hence, is the opposite of tail wind, the wind that blows in your front, making it difficult for you to advance.
In sprinting, since we’re at the subject, every athlete loves to have a little tail wind. They run faster because of it. And because of this, IAAF the International Association of Athletics Federations keeps a record of wind speeds at its track and field meets and doesn’t recognize results as world records if the tail wind is over 2 meters per second. That is to say, if you run in world record beating time in the 100 meters race with at over-the-limit tail winds, your clock time will only be recognized as a world best, but not an official world record.
Head wind? Doesn’t matter. If you run in world record beating time against a head wind, more power to you.
To sum up, the tail wind is a wind that blows in the same direction we’re heading. Therefore it is a good help.
