I really dont see how these hot climates are any worse than corresponding northern cities. I live in Chicago and we dont leave our house for 5 straight months in the winter and then there are 2 more months where the weather is consistently shit. Is a summer where its consistently over 100 for 3 months worse than the 6 ish months of not going outside that northern cities see?
