Is going on holiday of any benefit? New research shows that going on holiday makes you not only feel good while you’re there but also gain the health benefits for months.

Jetting off to destinations such as the Maldives cuts your blood pressure, helps you sleep better and bounce back from stress. The benefits last at least a fortnight longer than the vacation and can be felt for months in some cases where it is claimed. Experts say workers should always take their holiday entitlement (权利) each year, but as many as one in three don’t.

The study compared key health markers in holidaymakers visiting Thailand, Peru or the Maldives, with those in people who stayed at home and continued working. The average blood pressure of those on holiday dropped by six percent while the workers saw their blood pressure rise by two percent over the same period. The sleep quality of holidaymakers improved by 17 percent while that of the non-holidaymakers deteriorated by 14 percent.

The study also found the ability of vacationers to recover from stress, known as the stress-resilience test, improved by 29 percent. There was a 71 percent fall in stress-resilience scores among workers. Tests showed fallen blood glucose (葡萄糖) levels, reduced risk of diabetes (糖尿病), trimmer waistlines and improved mood and energy levels, with the effects sustained for at least two weeks after returning home.

The Holiday Health Experiment was conducted by tour operator Kuoni and Nuffield Health, the UK’s largest healthcare charity.

It's true that many dads in the wild aren't interested in parenting, but there are some that work pretty hard to give their little ones a good start. Maybe one of these dads will make you remember your own dad!

The male giant water bug doesn’t seem to mind a heavy load on his back for his kids. The female puts about 100 to 150 eggs on the back of the male, and then she leaves. Once the female is gone, the male has to look after the eggs. It usually takes one to two weeks for the eggs to hatch. The father giant water bug jumps around to make sure the growing eggs get enough air and water. All this time he can't fly because of the weight of the eggs growing rapidly on his back.

Now let's turn to the male stickleback fish. When the mother leaves after laying her eggs, the father tends his young. If the young fish go too far away, their father helps with their safe return by carrying them back in his mouth. The male stickleback looks after all his young — as many as 100 — until they can live on their own.

A similar example can be found in emperor penguins living in cold areas. The male emperor penguin goes without food while looking after his egg until it hatches. For about 62 to 67 days, the egg stays on top of the father's feet, in very cold temperatures that drop down to -39℃. As a result, the father may lose nearly 50 percent of his body weight while waiting for his baby penguin to be born!

In cities with rent control, the city government sets the maximum rent that a landlord (房东) can charge for an apartment. Supporters of rent control argue that it protects people who are living in apartment. Their rent cannot increase; therefore, they are not in danger of losing their homes. However, the critics say that after a long time, rent control may have negative effects. Landlords know that they cannot increase their profits. Therefore, they invest in other businesses where they can increase their profits. They do not invest in new buildings which would also be rent-controlled. As a result, new apartments are not built. Many people who need apartments cannot find any. According to the critics, the end result of rent control is a shortage of apartments in the city.

Some experts argue that the minimum wage law can cause problems in the same way. The federal government sets the minimum that an employer must pay workers. The minimum helps people who generally look for unskilled, low-paying jobs. However, if the minimum is high, employers may hire fewer workers. They will replace workers with machinery. Therefore, other things being equal, the number of workers that employers want decreases. Thus, critics hold the opinion that an increase in the minimum wage may cause unemployment. Some poor people may find themselves without jobs instead of with jobs at the minimum wage.

Supporters of the minimum wage say that it helps people keep their dignity. Because of the law, workers cannot sell their services for less than the minimum. Furthermore, employers cannot force workers to accept jobs at unfair wages.

Economic theory predicts the results of economic decision, such as decisions about farm production, rent control, and the minimum wage. The predictions may be corrected only if “other things are equal”. Economists do not agree on some of the predictions. They also do not agree on the value of different decisions. Some economists support a particular decision while others criticize it. Economists do agree, however, that there are no simple answers to economic questions.
