not an easy task
The growth of the human body ends at the age of 25, and the aging process begins immediately. To slow down or stop it altogether is a dream not only of scientists and philosophers who have been trying for centuries to find the “elixir of youth”, but also of each individual person. About a century ago, the science of gerontology arose, studying the biological, social and psychological aspects of human aging, its causes and ways to deal with it. A lot of scientific and pseudo-scientific theories of aging have arisen, over which whole gerontological institutes work, created in almost all countries of the world. There are a lot of theories describing the causes of aging – a change in the regulation of gene activity, a decrease in the synthesis of intracellular regulators of plasma membranes, a decrease in the length of telomeres (end sections of chromosomes), the concept of stress-age syndrome, etc. Continue reading
Engaging in physical education is not only useful, but also fashionable. Today, young people and middle-aged people regularly visit fitness clubs, train in sections or on their own. Someone trains every day, someone once a week, and each sets its own tasks – either to build muscle, or to gain a slender figure, or simply to maintain and strengthen health. It is useful to know in this case that according to the Scandinavian recommendations on nutrition and a healthy lifestyle (NNR), which are the most authoritative for the Nordic countries (including Russia), adults need to spend at least 150 minutes a week on moderate loads or more than 75 minutes per week for high-intensity loads. This means that you need to train at least two to three times a week. If this doesn’t work out like this, you can gain the necessary level of physical activity with daily morning exercises (at least 15-20 minutes) and walking, controlled by a pedometer (10 thousand steps per day).

The modern classification of vegetarianism has been formed for more than 100 years, having gone from partial rejection of meat (flexitarianism), rejection of meat, but with the assumption of fish in the diet (peskarianism) to a complete rejection of all animal products, including milk and eggs. Currently, there are mainly two directions: veganism and lacto-ovolacto-vegetarianism. Veganism is the most severe form, including eggs and animal milk (except human breast milk for babies). As a rule, the path to veganism passes through first of all awareness of the ethical problems of modern society and involves the maximum rejection of the use of products obtained through the exploitation and killing of animals.
The word vegan was proposed by the ideologist of this trend Donald Watson in the middle of the last century as an integral part of the first three and last two letters of the English word “vegetarian”. This term was introduced by the “Vegan Society”, founded by Watson in the UK. Continue reading
