Why do some people think that modern lifestyles are not healthy?

Many people believe modern lifestyles are not healthy due to increased sedentary behavior, reliance on processed foods, and high levels of stress associated with fast-paced living. The prevalence of technology and screen time often leads to reduced physical activity and social interaction. Additionally, the convenience of fast food and busy schedules can result in poor dietary choices, contributing to various health issues. These factors collectively raise concerns about the long-term impacts on physical and mental well-being.
