Just found out that visiting certain major cities could actually shave up to 3 years off your life—yikes! A new study says air pollution in places like Dhaka, Cairo, and São Paulo is so bad, even a short trip can mess with your health. Driving with the windows down? Apparently, that's the worst! If you’re heading to any of these spots, use air recirculation in your car, check the cabin filter, and skip the open windows. Who knew travel could be this risky? #TravelTips #AirPollution #TravelSmart #Travel
