Exercise 1
Isabel has turned down two job offers in the past year. In 2006, she started her own consulting practice, but by 2008, most of her larger clients had to drop her because of the economy. In 2011, she was undertaking irregular assignments and knew she needed a steady job. The first job she considered was Director of HR for a company in Utah. After the initial interviews, she felt the job fit her except the location. Still, she flew west to meet the hiring manager. The hiring manager explained that Isabel was the top candidate for the job but that, before she continued with the process, she should better understand the firm`s culture. She directed Isabel to several videos of the company`s CEO, who regularly appear in front of the company in costume as part of moral building exercises and expected his seni
or leaders to do the same. “Even though I was desperate for a job, I knew I couldn`t do that,” Isabel says. She called the recruiter to turn down the job and explain that she didn`t feel a cultural fit.
A few months later, she interviewed another job: a director of employee relations at a local university. After several interviews, the hiring manager told her the job was hers if she wanted it. The job has many positives: it was a low-stress environment, if offered great benefits, and the university was an employee-friendly place. But the job was relatively junior despite the tittle and
Isabel worried it wouldn`t be challenging enough. Finally, she turned it down. “It would be great to have a paycheck and great benefits but I would definitely have trouble sleeping at night,” she says. In both cases, she frank with the hiring managers about why she wasn`t taking the jobs. “In the past, it felt like dating, I was worried about hurting people`s feelings,” she says. However, they appreciated her frankness and thanked her honesty. She says it was hard to turn down the jobs and
it was a risk for her financially but she felt she had to. | |||||

Exercise 2
You do not usually get something for nothing. Now, a new study reveals that the evolution of an improved learning ability could come at a particularly high price: an early death.
Past experiments have demonstrated that it is relatively easy through selective breeding to make rats, honey bees and —that great favorite of researchers— fruit flies a lot better at learning. Animals that are better learners should be competitive and thus, over time, come to dominate a
population by natural selection. But improved learning ability does not get selected amongst these animals in the wild. No one really understand why.
Tadeuzs Kawecki and his colleagues at the University of Fribourg in Switzerland have measured the effects of improved learning on the lives of fruit flies. The flies were given two different fruit as egg-laying sites. One of these was laced with a bitter additive that could be detected only on contact. The flies were then given the same fruit but without an additive. F
lies that avoided the fruit which had been bitter were deemed to have learned from their experience. Their children were reared and the experiments was run again.
After repeating the experiment for 30 generations, the children of the learned flies were com-pared with normal flies. The researchers report in a forthcoming edition of Evolution that although learning ability could be bred into a population of fruit flies, it shortened their lives by 15%. When the researchers compared their learned flies to colonies selectively bred to live long lives, they found even greater differences. Whereas learned flies had reduced their life spans, the long-lived flies learned less well than even average flies.
The authors suggest that evolving an improved learning ability may require a greater investment in the nervous system which takes resources away from processes that delay ageing. However, Dr. Kawecki thinks the effect could also be a by-product of greater brain activity increasing the production of Reactive Oxygen Species (ROS), which can increase oxidation in the body and damage health.
