Carefully embedded and safely protected by a sturdy cage, our heart starts beating at about three weeks after conception and continues to thump away minute-by-minute, decade after decade until the day we die. We generally don’t pay attention to it unless something goes awry, it stops doing its job right, and causes us to delve into the wealth of information available about this wondrous organ.
