Heart Surgeon Reveals Top 4 Health Habits to Adopt After 40

On November 9th, 2025, a heart surgeon with over 25 years of clinical experience revealed the top four health habits that people should adopt after turning 40. Dr. Jeremy London, a board-certified cardiovascular surgeon based in Georgia, shared this crucial advice in a viral TikTok video that garnered over 2.6 million views.

According to Dr. London, the first two tips apply to all ages - avoid alcohol and quit smoking. He explained that alcohol is "toxic to every cell in the body" and urged viewers to limit or remove it from their lives. Similarly, he warned against smoking and vaping, which increase the risk of lung cancer, heart attack, and stroke.

The third recommendation from the surgeon is to prioritize sleep and avoid trading it for other activities. He acknowledged that this can be challenging, but emphasized the importance of rest and recovery, especially as people age.

Lastly, Dr. London advised his viewers to "avoid toxic people" and instead focus on nurturing relationships with those they care about, as that is what truly matters in the end.

Many viewers agreed with the doctor's advice, praising the benefits of quitting alcohol and the importance of maintaining healthy relationships.
