Competency-based medical education has put the onus on students to comprehend, understand, and apply the competencies learned to get promoted to the next level and to ultimately graduate. I enjoy teaching my students physiological concepts by helping them put on their thinking concept-applied physiology (CAPs). My Microsoft PowerPoint may have few slides instead of jargon of every explanation already given and explained in textbooks. I lay forward concepts and questions and allow students to pause in between my lectures. This gives them ample time to wear their thinking CAP and decipher the enigma of the human body through CAP. As adult learners, we give them a platform to rationally think and make concepts for we also learn and redefine our role as facilitators and mentors and not only feed them for rote learning. I am taking you all through the Cardiorespiratory–Renal CAP ride through this article. Let us all think out of the box to stimulate the joy of learning.
