New indicators for measuring aging

   Recently, researchers have described a method that can be used to assess the biological aging process. Related papers were published in "Nature-Communication".

  Aging is associated with worsening functional decline and increased risk of chronic diseases. Determining the biological age is very complicated and does not necessarily correspond to the age that changes over time. Various studies use blood markers, DNA methylation and other methods to develop biomarkers and predictors of aging, which are expected to be used clinically to determine anti-aging interventions The effect of the measures.

  Timothy Pyrkov and colleagues of Gero PTE in Singapore, using the British biobank and longitudinal human blood count data from a nutrition and health survey, developed a single variable describing biological age, which they called a "dynamic organism status indicator" "(DOSI).

  DOSI is related to expected variables such as age, disease, and lifestyle. Researchers say that changes in DOSI can be used as a measure of physiological resilience, indicating the ability to recover from disturbances (such as diseases). The authors found that the change in DOSI increased with age due to the increase in recovery time. They also used the gradual loss of resilience to predict the maximum human life span of about 120 to 150 years. These calculations are consistent with the results of other studies.

Moroccan football team: "The most familiar stranger"

   When I was still in college ten years ago, I led a sightseeing group of more than 30 Moroccan students. Before meeting them, my general impression of the Moroccans was that they are from North Africa but closer to the Arab world. They have religious beliefs, are used to worship, and are inextricably linked with France.   When I saw the real person, I realized that the North Africans in front of me were actually a group of children playing with each other and having fun in time. They were about the same age as me at the time. I have all kinds of nicknames and nicknames. During the process of taking them to Badaling, the Summer Palace and Houhai, two classmates and I, together with more than 30 Moroccan students, realized "cultural integration" and "world unity" in the small group to some extent.   During the World Cup in Qatar, I was surprised to find that the little-known Morocco team, which was eliminated in the group stage of the last World Cup, after miraculou

Zeigarnik effect

  As a freelancer, you have to fight procrastination every day. "I've made up my mind many times, but I just can't change it. Is it because I'm slow or slow?". In fact, many procrastinations are irrational. Many obstructions are imagined by myself. So distract, postpone, avoid confrontation. It's cool to procrastinate, and it's cool to procrastinate all the time, so I can't do it. Concentration is also related to physical strength. When the physical strength is exhausted, it is even more difficult to concentrate. You’ll tell yourself: I’m too tired to do this—okay, another perfect procrastination.   In 1927, Bruma Zeigarnik's senior research found that people are more likely to care about unfinished and interrupted work than completed work. This is the Zeigarnik effect. For example, we often don't care much about what we have got, but we will especially cherish what we have worked hard but haven't got. Therefore, the TV series will tell you
