Luis Cano, born in Colombia in 1914 and now residing in New Jersey, is recognized as the oldest living man in the United States at 111 years old. His longevity is attributed to simple yet effective habits: abstaining from smoking and alcohol, ensuring good sleep, and maintaining positive behavior. According to Dr. Praveen Gupta, Chairman of MAIINS at Marengo Asia Hospitals in Gurugram, avoiding smoking is critical as it is linked to major health issues like cardiovascular disease and cancer, which can shorten lifespan. Similarly, alcohol consumption is associated with liver disease and other health risks. Cano emphasizes the importance of good sleep, which supports metabolic function and reduces the risk of chronic diseases. Dr. Gupta highlights that emotional well-being and social connections are vital for longevity, as chronic stress can lead to serious health problems. Additionally, Cano's vegetable-rich diet and physical activity, such as gardening, play significant roles in his health. Dr. Gupta notes that while genetics account for 20-30% of lifespan, lifestyle choices like diet and exercise are key contributors, making up 70-80%. Overall, Cano's life serves as an inspiration, showcasing that longevity is influenced by a combination of healthy habits and access to healthcare.
