I find the airport center of innovation. Every time I travel I get to see something new. The premise is more efficient, making things get done quickly. Be it luggage drop, security check or getting your booking pass.
Once you are inside an airport, you find a complete cosmopolitan. People from various sectors, society, backgrounds immersed in a single place. Each has own reason for the travel: leisure, vacation or health reasons.
I also see elderly escorted by their sons and daughters.
With the advancement in technology, our lives have gotten much better. We are traveling more, spending more and have gotten closer to the world.
