Man is a complex being. Sometimes it is very difficult to understand the reason for his actions. People choose means largely on the basis of emotions and only secondarily on the basis of logical-empirical considerations. Take, for example, young people who willingly agree to experiment with hard drugs thereby running a risk to become addicted and ruin their life. If people were really rational, we would not need an active government policy to fight the spread of hard drugs, because all people would choose by themselves to abstain from these dangerous and damaging products.
