**Alcohol** affects people in different ways, and it does not only depend on physical characteristics or the type of drink. There are several **personal factors** that can influence how alcohol impacts a person. Among these factors are **stress**, pregnancy, and certain illnesses. These personal circumstances can make alcohol have a more pronounced effect on the individual.

Therefore, it is important to recognize that a person's emotional and physical state, such as stress, can modify the way alcohol affects their ability to drive. This reinforces the idea that alcohol does not only depend on physical factors or the type of drink, but also on the personal circumstances of each individual.
