The definition of ‘virtual’ in the dictionary refers to a presumed existence or subject that is treated as if it does not exist in reality. However, in contemporary usage, ‘virtual’ describes something that cannot be physically sensed by human beings. For instance, ‘virtual currency’ exists in the form of bits, as it cannot be perceived sensibly. Just because you can’t feel it doesn’t mean it doesn’t exist. In fact, human senses cannot detect the smallest unit of atoms that compose all things, yet that does not negate their existence. If something that does not exist but can exist as a hypothesis is called ‘virtual,’ then it exists in reality as a concept as soon as it is assumed! When something is hypothesized, the entity that is assumed originally did not exist, and the subject who made the assumption had not existed from the beginning, thus proving its existence by expressing the will of that assumption. Therefore, distinguishing between virtual and real holds no ontological signifi...
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”
