People often say that as one gets older, time passes more quickly, while in youth, time seems to move more slowly. The reason individuals feel that time goes by more slowly when they are young is likely due to a decline in memory. As children, people have limited experience, so everything feels new, and they tend to remember new things well. Having less experience translates to fewer memories. Because there are so many new memories, children perceive time as passing slowly. However, as people age, experience accumulates, and they typically become better at predicting situations, making it easier to cope, resulting in fewer surprises. Since these experiences are not exceptional, they tend to forget them, and when reflecting on the past, there’s little to recall, creating the sensation that time flies. Among the aspects of aging, what is scarier than the decline of the senses is the deterioration of expectations. If the flavor of food becomes predictable based on accumulated experience, ...
The "normal human body temperature = 37°C" standard was established in 1851 by the German medical doctor "Carl Reinhold August Wunderlich", who took millions of temperature readings from about 25,000 people and reported "36.2°C to 37.5°C". However, surveys in the United States in 1992 and the United Kingdom in 2017 found 36.8°C and 36.6°C, respectively. So in the past people deemed that the discrepancy was due to errors in old measuring equipment or methods. But Julie Parsonnet and her colleagues at Stanford University's School of Infectious Disease Epidemiology found a common thread in the temperature databases: People are cooler now than they were then. It wasn't just a measurement error. They speculated that medical advances had reduced inflammation and lowered the average temperature. We don't question the obvious. - Joseph’s “just my thoughts”
