我们说某人“一路走好”，通常是当一个我们熟识的人去世后所致的哀词。标题中的“身后”就是指一个人死后的意思。
按照现代社会标准到三十岁有下一代，一个人活九十岁平均寿命计算，我们普通人死后最多可被记忆六十年。或者说，当你死了六十年后，无论好坏善恶，基本上没有人再记住你，更别说怀念或感恩了。得到这样的结论道理很简单。首先假定你三十岁开始养育子女。当你九十岁离世时，你的子女六十岁。假定他们也是九十岁离世。因此，当你离世后你可被子女记住的时间是三十年。当然，孙辈也是能记住你的。当你九十离世时，孙辈三十岁。倘若孙辈寿命也是九十的话，理论上你可被孙辈记住六十年。前面提过，当你九十岁离世，孙辈三十，他们的子女刚问世，算是你的曾孙辈。但曾孙辈对你不会有任何印象，更如何让他们记忆你？因而，当孙辈九十离世后，你最后也行将成为百分百的一粒尘埃、落寂寰宇，再无人问津。那种感觉就好像你从来就没有存在过一样。事实就是如此简单，稍微有点冷酷。预测到这样的精准结局，是不是觉得未来其实有些悲催。
因此，活在当下，为己而活无疑是睿智选择。尤其当你尽责养育子女，他们成家立业。当你尽心孝敬父母，他们百年之后。这时的你也许在刚好停留在花甲之年，是应百分百为自己而活的时候了。因为你想再把握好的生活质量来日已经无多。如果你还要坚持形影不离照顾养育孙辈，就意味着这一生你将是一个彻底的失败者。在个人主义的积极意义上，你基本属于一辈子白活。
其实一个人身后即使被记忆一万年，对于个人的人生品味又有何意义？人生苦短，身后被记忆的时间更短。因此，活出你精彩的人生片段，体验你真实的生命感受。快乐与幸福仅在你自己的身体及心里足矣。
文章翻译成英文：
"Life Classic: Up to 60 Years Can Be Remembered Behind One’s Life "
When we say that someone is "gone well all the way", it is usually a mourning word after the death of a person we know. The "behind" in the title refers to the meaning of a person’s death.
According to the modern social standard there is a next generation at the age of 30, and the average life expectancy of the 90-year-old is calculated. We can remember up to 60 years after the death of ordinary people. Or, when you have been dead for sixty years, no matter how good or bad, basically no one will remember you, let alone miss or thank you. Getting such a conclusion is simple. First assume that you started raising children at the age of 30. When you died at the age of 90, your children were sixty years old, assuming they were also 90 years old. Therefore, you can be remembered by your child for thirty years after you die. Of course, grandchildren can remember you too. When you are 90, your grandchildren are thirty years old. If the life of a grandchild is ninety, in theory you can be remembered by your grandchildren for sixty years. As mentioned earlier, when you were 90 years old and your grandchildren were 30, their children had just come out and they were your great-grandchildren. But great-grandchildren will not have any impression of you, how can they let them remember you? Therefore, when the grandchildren died in the 90s, you will also become a hundred percent of a dust, a lonely, no one cares. That feeling is like you have never existed before. The truth is that it's so simple, a bit cold. Predicting such an accurate outcome, do you think that the future is actually a sad reminder?
Therefore, living in the present and living for oneself is undoubtedly a wise choice. Especially when you are responsible for raising children, they become a family. When you are dedicated to honoring your parents, they finally died. At this time, you may be just in the year of your sixty ages, it is time to live for yourself. Because you want to grasp the quality of life again, there are not many days left. If you still insist on taking care of your grandchildren, it means that you will be a complete loser in your life leftover. In the positive sense of individualism, you basically belong to a lifetime waster.
In fact, even if a person is remembered for 10,000 years, what is the meaning of personal life taste? Life is short, and the time spent being remembered is shorter. Therefore, live out your wonderful life fragments and experience your true life. Happiness experiences are good enough in your own body and heart.
