On average, water makes up about 60% of an adult male's body weight, meaning for a 150-pound individual, roughly 90 pounds of body weight is water. This percentage can vary significantly based on factors like age, gender, body fat, and hydration status.

The average human arm makes up approximately 5–6.5% of a person's total body weight. However, this simple percentage only scratches the surface of a complex question: what is the weight of an average arm when considering individual variations like sex, muscle mass, and fat distribution?

According to the U.S. National Academies of Sciences, Engineering, and Medicine, the recommended total daily fluid intake is approximately 3.7 liters for men and 2.7 liters for women, with the difference primarily based on average body size. So, do females drink more water than males? The data shows the opposite, challenging common assumptions about hydration.
