I read recently that scientists have identified a gene that is positively correlated with marital satisfaction. What the heck? This intrigued me since I am facing, I mean celebrating (😊), my 35th wedding anniversary with my sweet and long-suffering husband this week. It turns out that there is a gene that influences oxytocin (sometimes referred to as the “love hormone”) levels. People with higher oxytocin levels are more likely to report satisfaction in their marriage. Lower levels of oxytocin correlate with more anxious human connections perhaps stemming from low self-esteem and insecure past relationships.
It seems the genetic hand you are dealt bequeaths you an ancestral leg-up, or alternatively, a physical or psychological disadvantage. This is true when it comes to athleticism, for sure. I don’t spend a lot of time whining about the fact that I’ll never be an NFL running back. Sure, I’m not a bad runner for a 63-year-old woman, and I’m as competitive and disciplined as the next person. But other than that, I lack every essential physical attribute to perform at that level: age, strength, size, musculature, balance, and coordination. Oh well, maybe in my next life!
Genes play a role, too, in whether working out comes to us naturally, and the speed at which we develop an exercise habit. Our genetic makeup, for example, governs how easily we delay gratification, which is beneficial in forming fixed routines. Research has confirmed that there is a genetic component to couch potato-ism versus the motivation to enjoy physical activity. Genes influence whether weight training adds muscle, or, in some cases, additional body fat. In addition to oxytocin, the neurotransmitter dopamine also has a genetic component. Geneticists are investigating how dopamine levels are tied to motivation and how we perceive the desirability of certain activities, such as exercise.
But not to worry, lifestyle behaviors can mitigate or circumvent genetic inadequacies. I’ve read that genetic makeup is largely not deterministic of outcomes. Positive lifestyle choices such as exercise, nutrition, sleep, mindfulness, and social engagement affect the expression of many genetically-influenced physical and mental attributes. Good news for those of us who strive to live healthy and balanced lives!
As for the marital satisfaction gene, it’s cool that researchers have uncovered the oxytocin gene, but honestly, it might be more useful to see if there is a gene for putting the toilet seat down or taking out the garbage in bad weather. Now that would be something that all engaged couples would want to know!
