Article: When people get bad toothaches, they often have to eat soft, easily chewed food. When lions get bad toothaches, they eat people? That' s the conclusion of a zoologist at the Field Museum of Natural History in Chicago and a dentist who works on carnivores ., Lions don't normally prey on people. Every once in a while, however, a lion will go on a human-eating diet. The most famous such tragedy happened in 1898, when two lions killed and ate 135 railway workers in prefix = st1 /Kenya. Examining the preserved skulls of the two big cats, zoologist Bruce Patterson and dentist Ellis Neiburger found that both animals had been suffering from several dental and |aw problems. One lion had three missing teeth and a loose, unsteady lower canine that was probably useless. Canines are pointed teeth that hunting animals use for gripping and piercing prey ) .The two lions might have been so badly disabled that they couldn't bite down forcefully, say the researchers. Consequently, the lions might have abandoned their normal, more difficult prey and turned to humans. "Humans are easy preys, " said Patterson. "We're very slow, we don't hear very well, and we don* t see very well in the darkness. " The research calls their idea the Infirmity Theory. It was inspired partly by the work of Jim Corbett, a tiger hunter in Indiain the 1930s. Corbett was regularly called in to hunt tigers that had been dining on Indian villagers. Time after time, Patterson discovered that the killer tigers were suffering from some ill-healthy conditions.

Article: Do you know what Fear and Faith have in common? Fear believes in a negative future. Faith believes in a positive future. Both believe in something that has not yet happened. So I ask you, if neither the positive nor negative future has happened yet then why not choose to believe in the positive future? I believe during these challenging times we have a choice between two roads: the positive road and the negative road. And our bus can't be on two roads at the same time. So we have to make a choice and this choice determines our belief about the future and the attitude and actions we bring to the present. I'm not saying we shouldn't have any fear. There are times when fear is a gift. A healthy dose of fear causes us to examine our situation and plan for the future. It moves us to smell the cheese and expect change. When used wisely it allows us to manage risk and make better decisions. Some fear is good. However, what I have observed lately is a supersized, huge dose of fear that is spreading the hearts and minds of far too many people. This oversized fear is causing leaders and their organizations to either act unreasonably or to not act at all. They are either hurrying in a million different directions because of fear. In both cases, fear is leading them to take the negative road to failure. The answer is the positive road paved with faith and a belief that your best days are not behind you but ahead of you. With this belief you make the right choices and actions today that will create your positive future tomorrow. You stay calm, focused and committed to your purpose. You look for ways to save money and cut costs without making unreasonable fear-based decisions that sacrifice your future success. You identify opportunities in the midst of the challenges and you focus on solutions instead of problems. Your faith and belief in a positive future leads to powerful actions today. The future has not happened yet and you have a say in what it looks like by the way you think and act. Fear or Faith. The choice is yours.
Answer: both Fear and Faith trust something in the future

Article: To son, Cecil, Just a quick note before I start in earnest. When I wrote this, you were 8, still a little boy. In 2002, I was called to active duty in the Marine Corps in the war on Terrorism . On the 11th of September 2001 when America was attacked, I knew that I would eventually have to go and I was filled with a deep sense of sadness. That night as you and Keiko were asleep, I looked at your little faces and couldn't help but fight the tears. I knew it would be hard for you because I had a similar experience. When I was a little boy aged 6, my dad, your Grandpa Cawley, was sent to Vietnam during the war there. I remember how much I missed him, too. But now unfortunately I have come to realize just how difficult it must have been for Grandpa to be away from his children for a year. Thinking about this, I wanted to put my thoughts and feelings down for you and your sister. I am so sorry that I had to leave for such a long time. There is no place I would rather be than with you and Keiko. You two are the lights of my life. I have known no greater joy than in the few years since you two were born. I hope to have many more years with you. If this doesn't happen, then know that I love you more than words can express. If for some reason I don't make it home, I will need you to take care of your little sister and your Mom. You will be the man of the Cawley family. Be good my son and God will watch over you as he has me. I will be waiting impatiently for the time when we can all be together again.
