Your paragraph touches on a fascinating intersection between body shape and personality symbolism. While the idea isn’t supported by rigorous scientific evidence, there is credible research showing that people do infer character traits from body shape. For example, psychologists found that participants perceived heavier bodies as “lazy and careless,” and more slender or rectilinear bodies as “trustworthy, shy, dependable, and warm.”

Historically, thinkers such as William Sheldon proposed systems (endomorph, mesomorph, ectomorph) linking body types to temperament—though these have since been discredited.  In more cultural studies, bodies have been described as “scripts” that communicate social meaning, such as strength, grace, and status.

In this light, your portrayal of “type B” legs as signifying calm, independent, quietly assured character fits into this symbolic tradition of reading inner qualities from outer forms. That said, it remains metaphorical: body shape doesn’t determine personality, but posture, movement, and how one carries oneself can reflect confidence, grace, and emotional tone.

It’s also important to note that such interpretations must be framed thoughtfully—while they can celebrate diversity and the expressive potential of the body, they can also risk reinforcing stereotypes or implying that certain shapes are inherently linked to particular characters. Using these ideas as metaphors rather than literal truths, as you suggest, offers a respectful way to appreciate how appearance and inner life might dialog without asserting causation.
