Have you ever felt "where has the time gone?"

1. When the children grow up in a flash, I feel that time flies too fast

2. It feels like nothing has started this year yet, but when I look up, it will be September soon

3. During holidays, weekends, when you are happy...one is faster than the other

4. Time flies very fast, and you are old in the blink of an eye

5. It wasn’t until the moment I walked out of school that I felt that time suddenly sped up. When you were in your early twenties, you still felt like you were a baby, so why did everyone start to treat you like an adult all of a sudden? 6. I always felt like I was just a baby. After graduation, I realized that several years had passed

7. Maybe it was when I stayed up until three in the morning to finish watching the drama and woke up at twelve noon the next day;

8. After a busy week, it’s time to call my parents but I haven’t done so yet;

9. Summer is over, autumn has arrived, and it’s time to wear a coat;

10. Before I always feel that time is infinite and there are countless tomorrows waiting for me. Until one day I suddenly realized that time flies by so fast, I am no longer young, and I need to re-examine my current stage of life.

Why do you feel that time flies by so fast

In fact, this is caused by our increasing threshold for various stimuli. The so-called threshold value refers to the minimum amount of stimulation that can just cause us to feel. For example, what we usually call laughter is the funnyness of an event that just makes us laugh. Everyone’s point of laughter is different, and everyone’s point of laughter will continue to improve as the number of stimulating events increases. In other words, external things will become less and less likely to make you laugh. Therefore, everyone will feel that the Spring Festival Gala is getting less and less interesting, and the skits are getting more and more boring... In the same way, when we were children, everything felt fresh and interesting, and anything can easily attract you. According to the laws of time perception, novelty will make people subjectively feel that time is lengthening. When we do something for the first time, it feels like it takes a lot longer than doing the same thing again in the future. Even on the first day of a new company or the first day of vacation, time seems to pass very long.

Time speeds up as we grow up because the number of new stimuli we experience continues to decrease.
