From a neuroscience perspective, the object I love, devote myself to, and sacrifice for is an ‘extension of myself.’ The brain is inherently selfish. Selfishness is a necessary emotion and attitude for survival. Only when I exist can others exist. Yet, we often see people making sacrifices for others. How can I love someone other than myself? What I dedicate and sacrifice for someone is what my brain perceives as an ‘extended me.’ Ultimately, loving others is an extension of loving myself. Therefore, self-love becomes a foundation and a tool for loving others. If ‘self-love’ is healthy, then loving others is healthy too. - Joseph’s “just my thoughts”
In the USA, even in one country, the time difference between the west and the east is 3 hours. People thought that time was a natural thing. But it is not. It's very political. The time that man lives in a unit of minutes is too short. However, since the invention of the steam locomotive, the appearance of faster vehicles made crazy changes to the concept of time. The shift in distance made people realize what time was. Sandford Fleming, an engineer and inventor, asked to unify the time difference caused by long-distance transportation, but people rejected his request. If the boarding time were not fixed, the railroad would be useless. The history of the 24-hour clock was made only about 140 years ago. Even with the invention of high technology, if nothing is consensus, nothing benefits. - Joseph's "just my thoughts"
