Some people ask why I pay so much attention to the question of longevity. Am I afraid of it so much that I’m trying hard to avoid it at all? I’ll bet it’s on the contrary. I believe that ages can also give us a lot, for example wisdom and peace of mind. Yet there is another side of the coin – problems with health. And I know too well that it has influence not on the elderly people along but on everybody around them.

The recent study has shown that wives and other carers of men with prostate cancer may be at risk of anxiety, tiredness and other symptoms that influence on the quality of their lives. The results suggest that many family carers want help as well - for the sake of their own health and that of the cancer patient.

40 percent out of the 60 female carers in the study had significant anxiety symptoms, 12 percent were suffering from depression, and about one-third reported fatigue or sleep disturbances. According to the Journal of Clinical Oncology Another 15 percent complained of bodily pain. The women, who were mostly wives, aged 64 years old, on average, rates of each of these conditions surpassed the average for U.S. women of their age.

Scientists are sure that a high percentage of next of family carers experienced clinically meaningful levels of a number of symptoms. And those symptoms often took a strike on the women's daily lives. Those with higher levels of depression, anxiety and fatigue further had the lowest reckoning on a criterion degree of quality of life.

It was said that in estimated 44 million Americans care for an adult family member, and that number is expected to continue growing. Yet little has been known about how many of these carers suffer from their own psychological and physical symptoms. The current findings, though based on a small study, suggest that many family carers of cancer patients have serious health problems that demand attention.

So if you have a person who needs care in your family be very attentive to your own health. It is of much importance both for you and for your patient.

At last I've got the opportunity of writing something for people of age. Actually, this article will be useful for anyone because sooner or later we will all become older than we wish to. So, I’m going to tell you how to stay younger for a longer period of time.

British studies suggest that people who are physically active in their free time may be biologically younger than couch potatoes. The thing is that a sedentary lifestyle increases the propensity to aging-related diseases and premature death. Inactivity may diminish life expectancy not only by predisposing to aging-related diseases, in a certain way it also influences the aging process itself.

As I’ve already said this statement is based on researches. The researchers looked at the physical activity levels, smoking habits and socioeconomic status of 2,401 white twins. They also collected DNA samples from participants, and examined the length of telomeres-repeated sequences at the end of chromosomes in white blood cells (leukocytes). It is known that leukocyte telomeres shorten over time and may serve as a marker of a person's biological age. Overall, the study participants had an average telomere loss of 21 nucleotides (structural units) per year. However those who were more active in their free time had longer leukocyte telomeres than those who were not.

The authors of the research wrote that "such a relationship between leukocyte telomere length and physical activity remained significant after adjustment for body-mass index, smoking, socioeconomic status and physical activity at work". Actually there work showed that the most active subjects had approximately the same length of telomeres as sedentary individuals up to 10 years younger.

The exposure of cells to oxygen and inflammation brings to their oxidative stress damage which may be a factor contributing to shorter telomere length in static people. Forcefulness has also been linked to telomere length. Practice may shorten stress and its effect on telomeres and the aging process, the study authors suggested.

It is recommended to spend 30 minutes of moderate-intensity physical activity at least five days a week. Scientists suppose it can have significant health benefits. Consequently adults who partake in regular physical action are biologically younger than sedentary individuals. It provides a powerful message that could be used by clinicians to cooperate the potential anti-aging effect of regular exercise. However more research is needed to confirm a direct link between physical activity and aging.

We often notice that teens are too irritable and even aggressive from time to time. Some say that is the effect of poor breeding and parents’ inattentiveness towards their children. The researches have shown that it’s not quite so.

A study made by scientists of Australia and the United States has found that aggression in some teenage boys may be linked to overly large amygdalas, one of the regions in the brain involved in emotion and other functions. Scientists also suppose that these boys may also be not able to control their emotions because other parts of the brain that normally control strong emotions don't mature till the early 20s.

It is important for parents to keep in mind that while their teenage child looks like an adult and does very complicated work at school, parts of their brain are still developing. The process is going on in fact until the 20s. We are talking about those parts of the brain that are supposed to help the child control his own emotions and behavior.

In the study, 137 12-year-old boys and their parents were asked to discuss touchy issues, such as homework, bed times and Internet times; and the boys had their brains scanned later. It was noticed that boys who had large amygdalas spent more time behaving in an aggressive way, referring to a part of the brain located deep within medial temporal lobes that is believed to be involved with emotional responses, including arousal and fear. These boys appeared to have prefrontal cortexes as well, a region of the brain that has to do with regulating emotions.

So we can see that teenage aggression is deeply connected with boy’s mental development, which can be a good sign for the parents. But on the other hand the more intellect they have, the less control we have over their behavior.
