Based on the available information, age and gender can indeed affect alcohol moderation. Here's how:

Age: As people age, their bodies generally become less efficient at metabolizing alcohol. This means that it takes longer for the alcohol to leave their system, increasing the risk of harm [1]. The liver, which is responsible for metabolizing alcohol, often becomes less efficient with age. Therefore, older adults may experience the effects of alcohol more intensely and for a longer period of time than younger individuals [1].

Gender: Gender also plays a significant role in alcohol moderation. Women generally have less water in their bodies than men, which means that alcohol is less diluted in their systems [2]. As a result, women may experience the effects of alcohol more quickly and intensely than men, even if they weigh the same and consume the same amount of alcohol [2]. Additionally, women's bodies may produce less of the enzyme alcohol dehydrogenase, which breaks down alcohol in the body [2]. This can lead to higher blood alcohol concentrations in women compared to men, even after consuming the same amount of alcohol [2].

It's important to note that these are general trends and individual experiences can vary widely. Factors such as body weight, overall health, and the rate of alcohol consumption can all influence how alcohol affects an individual [1][2].
