Eye-catching new research: the subtle link between fertility and longevity.
A study led by the University of Michigan in the United States has sparked widespread discussion in the journal Science Advances. The study, which reviewed the genetic and health information of more than 276,000 people, provides strong support for the Williams hypothesis. The Williams hypothesis states that reproduction and longevity are significantly negatively correlated at the genetic level.
The study found that individuals who carried the mutation that causes higher fertility were less likely to live to age 76 than those who carried the mutation that caused the lower fertility. This means that mutations in genes that promote reproduction tend to shorten an individual's lifespan. However, researchers also point out that the relationship between fertility and longevity is influenced by both genes and environment.
Environmental factors play an important role in this association. For example, the impact of contraception and abortion on fertility, as well as the impact of medical advances on longevity, are factors that cannot be ignored. In addition, studies have also found that having only two children helps to have a longer lifespan when controlling the number and timing of reproduction of genes.
The results of this study have led to in-depth thinking about the relationship between family planning and individual lifespan. Notably, the study also reminds us that having too many or too few births can shorten lifespan. Therefore, in the pursuit of personal happiness and family planning, we should pay more attention to balance in order to achieve the best state of longevity.
So, let's have a second child!
Now, I invite everyone to share their thoughts on this topic in the comments section. What do you think are the implications of this study for family planning and individual longevity?Do you agree with the conclusion that having two children is the best way to live a long life?Let's start a discussion and share your thoughts!
