Where intellect and emotion clash, the heart often has the greater wisdom” wrote the authors of A General Theory of Love. In the past, they say, people believed that the mind should rule the heart, but science has now discovered the opposite to be true. “Who we are and who we become depends, in part, on whom we love.”
Each morning when I reach my office, I have one simple habit—check all my emails. Most of the time, I’ll work through them in a perfunctory fashion. There are some emails, however, that I’m eager to open. You guessed it—those from loved ones.
A while ago I attended a conference on the Middle Ages. In one seminar we actually prepared several foods that would have been common in medieval times. We used pestle and mortar to grind cinnamon and fruit to make jam. We cut orange rinds and broiled them with honey and ginger to produce a sweet snack. We crushed almonds with water and other ingredients to create almond milk. And, finally, we prepared a whole chicken to serve as a main dish with rice. As we sampled these dishes, we enjoyed a tasty culinary experience.
While traveling on an airplane with her 4- and 2-year-old daughters, a young mom worked at keeping them busy so they wouldn’t disturb others. When the pilot’s voice came over the intercom for an announcement, Catherine, the younger girl, paused from her activities and put her head down. When the pilot finished, she whispered, “Amen.” Perhaps because there had been a recent natural disaster, she thought the pilot was praying.
Once in a while my wife and I open the mail to find a letter with no words on it. When we take the “letter” out of the envelope, we see a piece of paper with nothing more on it than a colorful mark made with a felt pen. Those “letters” warm our hearts because they’re from our preschool granddaughter Katie, who lives in another state. Even without words, these letters tell us that she loves us and is thinking about us.
Dava Sobel’s award-winning book Longitude describes a dilemma faced by early sailors. They could readily determine their latitude north or south of the equator by the length of the day or height of the sun. Calculating east/west longitude, however, remained complex and unreliable until English clockmaker John Harrison invented the marine chronometer. This was “a clock that would carry the true time from the home port . . . to any remote corner of the world,” thus enabling sailors to determine longitude.
Our hearts pump at a rate of 70-75 beats per minute. Though weighing only 11 ounces on average, a healthy heart pumps 2,000 gallons of blood through 60,000 miles of blood vessels each day. Every day, the heart creates enough energy to drive a truck 20 miles. In a lifetime, that is equivalent to driving to the moon and back. A healthy heart can do amazing things. Conversely, if our heart malfunctions, our whole body shuts down.
