In an experiment, when people were asked to count three minutes in their heads, 25‒year‒olds were quite accurate, but 65‒year‒olds went over on average by 40 seconds. Time seemed to pass faster for the older group. This may seem meaningless, but there are a lot of benefits to perceiving time like 65‒year‒olds. For example, if you have been working on a project for eight hours, but it only feels like six, you will have more energy to keep going. If you have been running for 20 minutes, and you perceive it to be only 13 minutes, you're more likely to have seven more minutes of energy. So, if you want to use your energy to work longer, just change your perception of how long you have been working.

Sometimes conflict can be resolved through an expansion of resources. For example, a department may need five computers but has a budget for only three. However, by talking the finance people into delaying the purchase of other equipment, there will be more money left for departmental computers. Alternatively, the company may be reorganized and some people given early retirement, thus freeing up funds for computer equipment. An expansion of resources involves a reworking of the budget for the purpose of determining how additional funds can be found.

A child who hears a stern warning about the dangers of running in the street will have better self-esteem than a child who only hears that he's a bad boy when he runs into the street. The child who's a bad boy is getting the message that he and his behavior are not okay. He doesn't learn the difference between what he does and what he is. As an adult, his inner critic will attack both his behavior and his worth. Parents who carefully distinguish between inappropriate behavior and the basic goodness of the child raise children who feel better about themselves and have a far gentler inner critic.

Let's go back to our ancestors, back before elevators, escalators, cars, and even horses. This is when our human physiology was coming of age. Our ancestors had to move to survive. Not unlike most other mammals, humans had to expend much energy in order to acquire food and water. These early humans, with whom we share most of our physiology, were nomadic, and therefore moving was an essential part of their lives. As descendants of these nomadic people, our physiology is based on abundant movement and a diet of vegetables, fruits, nuts, fish, and infrequent, small portions of meat. To the extent we have that, we are more likely to be healthy. To the extent we don't, problems arise.

Some travel companies are very specific about what's included in the price quoted for a trip, but in other cases, you'll have to ask for details. Some meals might mean dinner but not breakfast or lunch, and sightseeing may mean a guide and local transportation but not admission fees or tips. Another good topic to investigate is your accommodations. Some tour operators don't commit to specific hotels but simply promise three- or four-star properties, so if you're particular about lodging, ask where the group stayed on past trips. And if you and your traveling companion want two separate beds, confirm that up front.
