How a “Bloodline Awakening” Later in Life Reveals Our Innate Genetic Hobbies and Interests

  Legend has it that once a person passes a certain age, a mysterious “bloodline awakening” will occur.
  The first people who discovered this were the group of young people who loved photographing flowers and clouds. Seeing the roses in full bloom, I couldn’t help but zoom in and take some close-ups. When I saw lotus flowers while walking by the lake, I immediately took a few photos. Opening the photo album, seeing red roses and pink lotus flowers, the young man’s expression suddenly changed – how could any one of them be a suitable avatar, a perfect match for nicknames from the older generation such as “The clouds are light and the wind is light” and “The still water is deep”?
  Then there is another group of young people who love to wear colors. When they were young, they always wore black, white and gray and thought they were extremely cool. I don’t know when they started walking on the road with cochineal red, dopamine powder, avocado green, and periwinkle blue with the momentum of a palette. They couldn’t understand why they missed 99% of the colors in the world in the past few years. They felt that Only aunts like to wear colors!
  There are also young people who love buying gold, fishing, and gardening. They used to think that these things were too boring, and somehow they fell into the trap and made a sound of “really delicious”. Is there really such a thing as bloodline awakening in the world?
  Each of us inherits half of our genes from each parent and acquires approximately 70 genetic mutations.
  What these DNA determines is not only whether our height is 1.6 meters or 1.7 meters, but also whether we have single eyelids or double eyelids. There are more subtle and complex traits that are also influenced by genetic inheritance. For example, hobbies.
  The British Family History website conducted a survey of 2,234 British people and found that almost a quarter of British people have the same interests as their ancestors. Many people’s love for sailing, fishing, stamp collecting, and dancing may be true. “Inherited from the same origin.”
  Do you like cilantro? A 2012 study found that just a small variation in the olfactory gene OR6A2 can affect people’s love for coriander by 8.7%.
  Do you like coffee or tea? A 2018 paper in Scientific Reports showed that genetic variation causes people to have different sensitivities to different bitter tastes, which can affect your beverage preferences. People who drink a lot of coffee are mostly sensitive to the bitter taste of caffeine but not sensitive to the bitter taste of quinine. People who drink a lot of tea, on the other hand, are sensitive to the bitter taste of quinine.
  Do you like to exercise? A 2020 paper in “Behavioral Genetics” studied 50,690 people and found that the “heritability” of exercise is about 34% to 41%. Compared with individual sports such as jogging, the “heritability” of team sports such as football is 13% higher. A 2022 paper in “Medical Science of Sports and Exercise” found 19 mutation sites related to whether they like to exercise or not from the genetic data of more than 157,000 people. If you’re genetically predisposed to enjoy the feeling of sweating, you’re more likely to enjoy exercising. If your parents love playing basketball and swimming, and you also switch back and forth between the stadium and the swimming pool, then your love for fitness is probably not only inherited through your ears, but also passed down through your blood.
  But why does one’s bloodline awaken after a certain age?
  Because when we are young, we are more affected by our environment. Young people are usually more concerned about other people’s opinions and will follow trends under “peer pressure” – wear trendy brands, go to places where Internet celebrities check in, and follow the hottest variety shows. The unique parts of young people are easily obscured by popular trends. But as we get older, we become more and more accepting of ourselves “as we are.” So the genes inherited from my ancestors began to express actively. It doesn’t matter what others think of me. Let the silk scarves, fishing, pink, and lotus flowers come more intensely!
  In addition, young people are usually economically weaker and unable to determine their own environment. Genes are like seeds, and the environment is like soil. When the soil is not suitable, it is difficult for seeds to grow and bloom. Even a genius like Einstein, if he had been born in the Middle Ages, would have had no choice but to agree with the geocentric theory against his will, and it would have been impossible to come up with the theory of relativity single-handedly. But as you get older and your wallet becomes bigger, you can now buy things that you couldn’t play with when you were young. The “adult toys” that have been popular in recent years and “children’s toys are too childish, but adults’ toys are just right” are all expressions of genes that were suppressed when they were young and rebounded with a vengeance when they grew up.
  The greater the environmental pressure, the less room for genes to perform. For example, studies on the heritability of exercise also show that partners who live together often influence each other’s exercise habits. If your partner loves walking, you might just follow along with a grimace. But if the environment is “tolerant and free” to us, genes will have more room to play, and the influence of genes will be more obvious.
  Of course, a hobby cannot accurately locate a certain gene. Hobbies are complex traits that are often influenced by multiple genes. To be sure, genes are not “destiny.” Genes are more like a pair of hands that gently push us. We may not go in the direction that genes push us.
