The new science of spending comes to a surprising conclusion .How we use our money may as much or more than how much we’ve got it.
Money spent on experiences , rather than material goods, more happiness.

And experiences come with one more . They tend to bring us to other people , but more often, material things are enjoyed .So social contacts are important to mental and physical health.

Another secret of animals’ survival is telepathy（心灵感应）. This sense becomes atrophied（衰退） in man, but a(n) thought-communication functions in animals. Elsa, the lioness, frequently when George and I intended to visit her camp, even though it 180 miles from our home in Isiolo. On most when we made our irregular visit she was waiting for us. By following the spoor（野兽的足迹），we that she had sometimes walked 50 or 60 miles to meet us.
The same thing when I took Elsa’s sisters to Nairobi to be flown to the Rotterdam zoo, Elsa’s zoo. Elsa stayed behind with George in Isiolo 180 miles . He did not know when I was coming back, no person knew. But Elsa knew. On the morning of my she sat down at the entrance and wouldn’t make any until I arrived in the evening.
I have known this kind of thought-communication with the animal with whom I’ve lived. When Elsa died, I woke in the night, knowing what had happened, even though I was several miles away. The same thing later with one of Pippa’s cubs.
I don’t this sensitivity with my own kind. Feel far more in tune with what is going on when I am in the bush than when I am in London on Nairobi. We don’t know much yet about this telepathy from which gland（腺体） it comes, or how it . But if men could awaken or it in themselves, and then cooperate by trusting each other, fearing and treating one another , the world would be a far better place.

Many theories regarding the causes of juvenile delinquency（crimes committed by young people）focus either on the individual or on society as the major contributing influence．Theorieson the individual suggest that childrencriminal behavior before they were not sufficientlyfor previous misbehaviors or that they have learned criminal behavior through interaction with others．Theories focusing on the role of society suggest that children commit crimes into their failure to rise above their socioeconomic status or as a rejection of middle-class values.
Most theories of juvenile delinquency have focused on children fromfamilies，the fact that children from wealthy homes also commit crimes．The latter may commit crimes for lack of adequate control from parents．All，however，are uncertain or unimproved and are of course challenged with criticism.
Changes in the social structure may indirectlyjuvenile crime rates．For example，changes in the economy thatto fewer job opportunities for youth and rising unemployment make gainful employment increasingly difficult to obtain．This results inamong youths and may inlead more youths into criminal behavior.
Families have also experiencedthese years．More families consist of one parent households or two working parents；，children are likely to have less supervision at home than was common in the traditional family．This lack of parental supervision is thought to be an influence on juvenile crime rates．Other noticeableof offensive acts includeexperience or failure in school，theavailability of drugs and alcohol，and the growing phenomenon of child abuse and child neglect．All these conditions tend to increase theof a child committing a criminal act，a direct cause and effect relationship has not yet been established.
