Which of the following factors does NOT affect a person's Blood Alcohol Concentration (BAC)?

Blood Alcohol Concentration (BAC) is influenced by various physiological and environmental factors that affect how alcohol is absorbed and metabolized in the body. Among these, gender, weight, and muscle/fat ratio are all significant contributors.

Gender affects BAC because biological differences between males and females influence body composition and how alcohol is processed. Generally, females tend to have a higher body fat percentage and lower water content than males, which can result in a higher concentration of alcohol in the bloodstream when consuming alcohol in equal amounts.

Weight is another important factor because a person with a higher body weight typically has a larger volume of body water, which can dilute the alcohol consumed, leading to a lower BAC compared to someone with a lower body weight who consumes the same amount of alcohol.

The muscle/fat ratio also plays a role since muscle tissue contains more water than fat tissue. This difference means individuals with a higher muscle mass may experience a lower BAC compared to those with higher fat content when consuming alcohol.

Age, while it can influence overall health and metabolism, is not a direct factor affecting BAC like the others mentioned. The way alcohol is processed may change as people age due to variations in metabolic rates, but age itself does not create a direct effect on BAC calculations.
