Hostility was the characteristic that contributed to Marvin's health problems.

In stressful situations, the type A personality pattern is distinguished by easily showing a high level of hostility in the form of verbal, gestural and even physical aggression. These individuals have a tendency to stress easily and stress can cause various health problems.

Type A hostility is also observed because they are people who quickly raise their voices and use a threatening, almost unnoticed, tone automatically.
