Get ready to turn back the hands of time on Biological Clock Day on April 28! This day was created to bring awareness to the human body's internal clock and its effects on aging and overall health. The term "biological clock" was first coined in the early 20th century, but it wasn't until recent years that scientists have delved deeper into understanding its mechanisms. While some may view this day as a reminder of getting older, let's see it as a chance to learn more about our bodies and how we can take care of ourselves both physically and mentally. So let's celebrate our amazing biological clocks and all the wonderful things they do for us!
