Dr. Jeremy London, a cardiothoracic surgeon, has returned with more practical advice on how to live healthier and improve our overall quality of life. In a recent TikTok video filmed with his sons, he highlights several things people over 40 should avoid—though he points out that these habits are worth breaking at any age.
In the clip, one of his sons steps in and asks, “Dad, what should people avoid once they hi:t 40?”
Dr. London responds, “The top two apply no matter how old you are. Number one is alcohol.”
He continues, “If you want to set yourself up for long-term health, cut back or eliminate alcohol. It’s toxic to every cell in your body. I know it’s tough because alcohol is everywhere, and it’s a personal choice—but be intentional about it.”
The Cleveland Clinic also cautions that alcohol causes more damage than most people realize. Besides contributing “empty calories” that lead to weight gain, long-term drinking raises the risk of serious issues such as heart disease, liver cirrhosis, several types of cancer, and even cognitive decline.
Research supports these wa:rnings.
A major study published in The Lancet concluded that the safest amount of alcohol is actually none, indicating that even moderate consumption has measurable negative effects.
An occasional drink may not be catastrophic, but many health professionals agree that reducing alcohol intake especially after 40 is one of the smartest choices for long-term wellness.
Dr. London’s next wa:rning is about smoking and vaping. “These are obvious,” he says. “They increase your risk of lung cancer, heart attacks, and strokes. Don’t vape, don’t smoke.”
He also emphasizes the importance of adequate sleep, noting how often people sacrifice rest for other activities. “Don’t trade sleep for anything else,” he admits. “This is something I personally struggle with. Recovery is essential throughout our lives, but especially as we age.”
Finally, he offers one more piece of life advice: “Stay away from toxic people. Invest in the relationships that matter—those built on care and love—because, in the end, that’s what truly counts.”
