 The text discusses the impact of poor visibility on people's behavior and health in Dubai, particularly during sandstorms. It highlights how reduced visibility can lead to increased stress levels, heart rate, and blood pressure, as well as decreased cognitive function and mood. Additionally, it mentions that older adults may be more susceptible to these effects due to age-related changes in their bodies. The article also touches upon the importance of shielding the human brain from aging and the potential benefits of using certain techniques to improve cognitive function.
