     When you see geese flying along in V formation, you might consider what science has discovered

as to why they fly that way.

     As each bird flaps wings, it creates an uplift for the bird immediately following. By flying in V

formation, the whole flock at least 71 per cent greater flying range than if each bird flew on its own.

Individuals who share a common direction and sense of community can get where they are going more

quickly and easily because they are travelling on the pushing force of one another.

     When a god se falls out of formation, it suddenly feels the drag and resistance of trying to go it alone,

and quickly gets back into formation to take advantage of the lifting power of the bird in front. If we

have as much sense as a goose, we will stay in formation with those people who are headed the same

way we are.

     When the head goose gets tired, it moves back in the formation and another goose flies point. It is

sensible to take turns doing demanding jobs, whether with people or with geese flying south.

     Geese honk from behind to encourage those up front to keep up their speed. What messages do

we give when we honk from behind?

     Finally -and this is important -when a goose gets sick or is wounded by gunshot, and falls out of

formation, two other geese fall out with that goose and follow it down to lend help and protection.

They stay with the fallen goose until it is able to fly or until it dies, and only then do they launch out on

their own, or with another formation, to catch up with their group.

     If we have the sense of a goose, we will stand by each other like that.
