The symptoms of depression in men often show up in ways that people do not expect. For example, clinical depression is more frequent among women than men. Women have more suicide attempts than men. But among those who attempt suicide, men are more likely to die from their attempt at suicide. Depression should always be taken seriously because it has the potential of being lethal. Not all people die from cancer, but it is nevertheless true that cancer can kill. Not all people die from depression, but it is nonetheless true that depression can kill (via suicide).
