Arey, in our evolution, the four-chambered heart allows complete separation of oxygen-rich and poor blood, which supports our high energy needs—unlike the frog's three chambers that mix blood a little, suiting their slower life. But studying this, I see farmers' hearts failing under debt as much as anatomy; their stress weakens chambers no textbook shows. My own heart feels heavy when I arrange my bamboo desk files, thinking how their burden is not of chambers, but of worries we must mend.
