ISFps often have a characteristic stout or chubby, rounded figure. They often have short legs and a bouncy gait, giving the impression of a big springy ball. Their faces are usually smooth and round without any obvious projections. In moments of passionate conversation they can often swallow air like a fish. When ISFps try to explain things, they can move their eyebrows considerably.
ISFps generally appear to be soft-hearted, but can become quite assertive if required. Their facial expression can change suddenly and unexpectedly from friendly one to a stern one, especially when they wish to distance themselves psychologically from someone. ISFps are often inclined to give advise concerning will power and initiative.
