^^Yes, I too felt the same when I left Trivandrum for Chennai about a decade back. In the process of gaining experience one does have to compromise on the quality of life.^^Infact Bangalore dont have much 'good concrete jungles' than TVM. On a percapita basis TVM has better concrete and asphalt.
In BLR you dont feel like mixing up with the city, mostly it is dusty, chaotic, dirty except the old cantonment areas. So from your apt basement, in to the cozy confines of your car, and then escape to your office, perhaps then to a hotel, or shopping mall and then back to apt. You wont feel like roaming around the city on holidays. In TVM I used to go for drives within the city for relaxation, it is a bit more orderly and not much mixed traffic. In BLR you will get mad if you spent more time in roads. I had to change my car's clutch plates within 3 months of drive here. In BLR we need to live in a cocooned life to be comfortable. But overall I like the experience for the fact that it teaches you many things. I would say if want to experience what is India, you will need to go out of TVM or Kerala. Back home, the life is resort like, healthier and luxurious.
