In his latest memoir, “Greenlights,” Matthew McConaughey shares intimate details about various aspects of his life, including his pursuit of the true meaning of existence and his choice to wed his current spouse, Camila Alves.

However, one particularly striking revelation is the account of how his father met his demise while engaged in a romantic encounter with his mother, as reported by USA Today.

James Donald McConaughey, the actor’s father, tragically departed in 1992 at the age of 63.

Recalling the moment he received the distressing news, McConaughey writes in his memoir, “I received a phone call from my mother informing me of my father’s passing.

‘Your dad has passed away,’ she said.

My legs gave out beneath me.

It was unfathomable.

He was my father, a seemingly invincible figure.

Yet, it happened just as he had always jokingly predicted to me and my siblings, ‘Boys, when I meet my end, I’ll be with your mother.’

And indeed, that was the case.

His heart gave out during a moment of climax.”

The occurrence of cardiac incidents precipitated by s**ual activity is not unheard of.

This phenomenon is attributable to the fact that engaging in s**, like any form of physical exertion, elevates the heart rate, as previously elucidated by SELF.

The heart rate commences its ascent in the initial phase of the s**ual response cycle, termed desire, and reaches its zenith during orgasm, alongside an increase in blood pressure and respiration.

When the heart beats excessively fast, it may lead to tachycardia, a medical condition characterized by a heart rate surpassing 100 beats per minute.

Factors contributing to tachycardia encompass preexisting cardiovascular ailments, hypertension, genetic predisposition, and advancing age.

While occasional spikes in heart rate beyond 100 beats per minute are normal due to activities such as exercise or daily stressors, tachycardia entails the heart accelerating beyond its typical pace for abnormal reasons—exceeding what it can endure—which may culminate in heart failure, stroke, or a heart attack, according to insights from the Mayo Clinic.

Certain risk factors heighten the likelihood of these potentially fatal outcomes, including obesity, stress, smoking, and sedentary behavior.

Men aged 45 and older, akin to McConaughey’s father at the time of his incident, are also at an escalated risk of experiencing heart attacks specifically.

Furthermore, a heart attack has the potential to trigger the onset of a critical medical situation known as cardiac arrest.

It is crucial to recognize that while a heart attack can precipitate cardiac arrest, and an elevated heart rate can incite both conditions, they are distinct medical occurrences.

A heart attack transpires when a primary artery of the heart becomes obstructed, impeding the normal circulation of blood to the organ, as explained by cardiologist Jennifer Haythe, M.D., who serves as an assistant professor of medicine and co-director of the Women’s Center for Cardiovascular Health at Columbia University Medical Center, in earlier discussions with SELF.

On the contrary, cardiac arrest arises when the heart ceases beating altogether or adopts a perilous and irregular rhythm.
