A professor said that as long as men and women meet for the first time, if the body temperature is kept at 38 or 6 degrees Celsius, the chance of falling in love at first sight will be as high as 80%. The body temperature is generally around 37 degrees. When I meet my lover, my heart beats faster, my hormones are secreted too much, and my body temperature rises to 38 or 6 degrees, which is just a subtle but real half degree, which gives people a sense of security when the baby returns to the uterus.
