Q: Article: Howling is a behavior commonly observed among a wolf nark. An animals, wolves work together to hunt and rely on howling was an important means of communication each other. There are different explants of a wolf's howl and it appears that there may be more to discover. One theory is that wolves howl to bend better together. It's almost as if howling together helps the pack stay together. Perhaps something similar to people feeling a sense of involvement with each other when singing a song together . But this theory may be wrong, explains Fred H. Harington, a professor who studies wolf behavior. Indeed, there have been tines when wolves have been seen one moment howling in a exhorts, and the next, quarreling anions each other. It appears that usually the lowest-tanking menthes of the pack may actually be "punished" for Joining in the churs at times. So is howling a way to strcagthen a social boad or just a way to reconfirm status among its members? ----Why do welves howl for sure? What is cleat, however, is that howling is often used among packmates to locate each other. Hunting grounds are distant and it happens that woloves may separate from one another at times. When this happens, howling appcars to be an ercellent means of gathering. Howling, interestingly, is a contagious behaviour. When one wolf starts to howl, very likely others will follow. This is often seen to occat in the morning, as if wolves were doing some sotr of "roll rall"where wolves all howl togeter to howl, very likely others will follow.

Q: Article: Do you usually go Dutch(AA) when you take someone out to dinner? Do you expect your date to pay for the whole meal? Many people say that as long as there's love, money doesn't matter much. But this might change when the relationship gets serious and it is related to the money borrowed from the bank, the family present accounts and debt. A survey among 8 million couples in the UK suggested that 44% of married couples don't know exactly what their partner earns. An astonishing 23% actively try to keep their finances secret from their partners. About 38% of them are open to each other. Another 12% refuses to tell the truth. British relationship expert Russell says: "It's very difficult to talk about money. Often there's guilt, there's shame. To start those conversations is difficult. Money can be about how we value ourselves, how we feel valued. It's not just a simple case of talking about hard cash." So if you are in a couple, it might be a good idea to check if you both are on the same page about money before bills pile up on the kitchen table and love flies out of the window. When moving in together, couples should not only talk about their personal habits but also about their financial ones. Russell has a word of advice: "Accept the fact that in your relationship you might do money differently - there might be a spender or a saver. It's very attractive if your partner does things differently to say they're wrong. Do it differently but plan it well." And now, back to that date. Would you be bored with someone who was attractive but expected you to pay the bill by yourself? There's food for thought.

A: How many people are very careful not to let their partner know their income?

Q: Article: I was born in Brooklyn. My father was a small-business man and we never had much money. He supported the family, moved us to Merrick on Long Island, when I was 11. He just recently died at age 96. He was still driving and playing golf right to the end. He was the only guy I knew who at age 90 could shoot under his age. I guess that taught me something about perseverance. I went to the University of Michigan as an engineering student in 1960. I was standing outside the student union building when Senator John F. Kennedy made a campaign speech that essentially announced his plan for the Peace Corps. He talked about how students could provide service for the country. It was an important moment for me. After I graduated, I worked as a computer programmer for I.B.M. for two years. By then, the Vietnam War was in full swing and the draft had accelerated. I didn't agree with the war and was interested in finding alternatives. I.B.M. applied for a delay for me twice but the application failed. I went to work at M.I.T.'s Instrumentation Labs on a project designed to create a rescue vehicle for lost submarines . I thought this job would keep me out of the draft, but M.I.T. hadn't put in the proper paperwork and I got called in for my physical. The day before my physical, I broke my ankle playing tennis and, of course, my draft board didn't believe a word of it. I had to provide X-rays. I had tears in my eyes from the pain, but a smile on my face. I started John Snow Inc. in 1978 (Dr. Snow is considered the father of modern epidemiology because he traced the source of a cholera epidemic in the 1850s). We had a very clear vision of what we would be. It would not be about making the most money but having the most impact. My goal was to attract talented people who had that passion to focus on primary care, women's health, child health, and to do great work. I also run a nonprofit called World Education, which focuses on literacy. What motivates me is going to the field, either in the United States or overseas, and seeing the people whose lives we affect. I didn't grow up rich but had the advantage of growing up in the United States and getting a good education. I couldn't have started J.S.I. in many other places. And I believe there is a duty to try and assist people who are struggling against tough situations.
