Comparative Estimate of Life Years Lost University of Chicago's Energy Policy Institute (the same source cited in your article) provides the most consistent comparative estimates. Their 2023 report offers a stark picture: · Delhi: The most polluted megacity in the world. Residents could lose 11.9 years of life expectancy relative to the WHO guideline (5 µg/m³), and 8.5 years relative to the national standard (40 µg/m³). · Lucknow: As per annarticl, residents lose 6.5 years relative to the WHO guideline. The AQLI data often shows an even higher figure, closely aligned with the broader Indo-Gangetic Plain. · Hyderabad: Residents could lose approximately 3.5 - 4.5 years of life expectancy relative to the WHO guideline. Its from Times of India, numbers are generally better than the northern cities but still dangerously high. · Pune: Similar to Hyderabad, residents could lose approximately 3 - 4 years relative to the WHO guideline. · Bangalore: Slightly better than Hyderabad and Pune, ...
# A 2022 study found something striking: older adults with slower walking speeds showed signs of smaller brain volume and were more likely to experience cognitive decline. It's not just about stiff knees or tired muscles. Walking is much more than a physical act Here's what Dr Arun L Naik, MCh (Neurosurgery), AIIMS New Delhi, has to say about how this simple activity could be a predictor of cognitive health. # Movement as a mirror of the mind When the legs move, a network of brain regions lights up. Every step calls upon the frontal lobe (for planning), cerebellum (for balance), and spinal cord (for signal transmission). Even the feet send sensory feedback back to the brain. This partnership between brain and body means that walking isn't just exercise, it's a real-time reflection of cognitive health. Subtle changes in gait or coordination might actually be early warnings, long before memory lapses begin. Walking patterns have, in fact, been shown to shift years before...
