It sounds like you have a very sensitive sense of smell and you would not do well in India.
But for others - if the point of travel is to have new and novel experiences, and your senses being the primary entry point for experiences, India is the most intense sensory experience I've ever had - the smells, the sounds, and the sights all combine to overwhelm.
As would be expected with a developing country of over a billion people, not all sensory interactions are positive, but with the bad comes far more good, and a worthwhile distinct experience.
