The recent conclusion of two aerodynamic specialists at the California Institute of Technology is that large migrating birds fly in V-formation for practical reasons. It appears that by flying in this pattern the birds boost each other and increase their flight range as much as 71 percent. The theory is based almost entirely on laws of aerodynamics, rather than observations of birds in flight. But the V angles and spacings that these specialists arrived at in their calculations are very similar to those seen in flights of migratory birds.
According to their conclusion, each bird in flight leaves a strong updraft or upward movement of air off its wing tips. By taking a position in the formation so as to have full advantage of this lift, the bird following is helped to fly forward more easily. This is very much like the way a hawk or glider pilot takes advantage of updraft to keep aloft. Flying in this way reduces the forward speed of the birds, but it extends their flight range. And when you consider how many hundreds of miles migratory birds travel you can appreciate why this type of flying is far more practical.

Animal doctors? Why, that may sound like something out of a child’s storybook. Yet it is a fact that many animals are quite successful when it comes to treating their ailments. And they do this in ways that frequently prove to be more effective than those used by man. Yes, animals have been endowed by the Creator with an instinctive ability to treat themselves when they have certain afflictions.
Archibald Rutledge, a writer and naturalist, recalls that when he was a plantation boy he kept many wild animals as pets, one of them being a little white-tailed deer. One day he found that his pet had torn a nasty gash in its side on a barbed-wire fence. To help heal the wound, he cleansed it and carefully bandaged it.

Books have been with us for as long as we know it. And it serves us a lot of purpose. From bookkeeping history and keeping track of other major events in the past, to informing us with a lot of knowledge; and from capturing our imaginations to telling us bed time stories before we go to bed.
So we are really thankful for having those books, and for the one who invented this amazing literature work. Because without them, there will be no progress, and we might been living in a prehistoric age where people are not civilized. That might sound absurd or far-fetched, but our life without the book, that kind of possibility may not be that far.

Shopping malls are one of the places where people would love to hang out, dine, shop, and rendezvous. There are just a lot of things to do, stalls to visit, and restaurants to dine inside a shopping mall. And malls have been a part of our daily life and culture.
We Filipinos can’t live without the mall, because it has been a part of our life. And we can’t simply last a day if the entire mall here in our country were to close down. We all are really thankful for the ones who brought the mall here in our country.
