Shoulders slope like a trapezoid, long arms and large hands (the hand extends past the trouser seam), dry skin that creases early, high body temperature, and a face that tends toward an inverted triangle. RGP describes it as the Scandinavian, cold-climate biology.
RGP links this biology to heart problems and to skin cancer risk, especially with strong sun. Heat is its stressor. Educational context only, not medical advice.

RGP associates it with northern European ancestry, for example the Basque and Galician north of Spain.
Decisive under pressure · clear goals · courage with risk · produces results · natural leadership · resilient · moves people toward a goal.
Impatient with slowness · short fuse · hard to take criticism · dominates conversations · pride makes apology hard · reads vulnerability as weakness · rushes decisions.
Direct and brief. Wants the action, not the backstory. Listens for 'so what do we do?'.
Confronts head on and can turn authoritarian or sharp. Needs to win, and yielding feels like losing status.
Thrives in leadership, high-stakes sales, crisis management and building companies. Needs autonomy, clear goals and pace.
Most common ground with Sanguine (both hot) and Melancholic (both dry). Least in common with Phlegmatic (opposite). RGP notes that choleric people often struggle to ask a partner for care, and that ruptures are common when the temperament is not understood.
Leads without needing to flatten anyone. Builds status while making sure competitiveness does not hit the wrong person.
Uses intensity defensively, rarely asks to be cared for, and tends to collect ruptures.
Loosen pride, anger and obstinacy. Learn that yielding control is not losing, and that other people's pace is not an attack on your leadership.
