For people who suffer from concrete, tangible fears (fear of pain, misfortune, illness, poverty, fear of the unknown). They keep their fears to themselves and rarely talk to others about them. They are often physically delicate and sensitive. When interacting with other people, they blush easily, stutter, giggle nervously, or get sweaty palms. Hypersensitivity to noise, cold, loud speech, crowds of people is also typical.
