Kolkata is a huge city, and is also very congested as it has a population of about 4.5 million. It is also a city with a lot of poor people and it is very common to see people sleeping by the sidewalk. You also see whole families camped or just sleeping out in the open. It is just heart wrenching. As a lot of people here are homeless, they also don’t have their own toilets, so they just urinate or do their business on the side of the streets. One more thing I noticed is that most restaurants or street vendors here still cook with charcoal or kerosene stoves. Everything about Kolkata just feels so old. It’s just like stepping back in time as most of the city hasn’t changed for the past 50 years.
