You can't disinfect India

It's great to see so many Asian tourists travelling in India, and I was amused to sit opposite a couple of Thai girls on the train to Agra and as they got on the train they sprayed their seats, either to disinfect them, or make them smell nice I'm not sure. However it is impossible to disinfect India, and this is one of the biggest things you have to get used to. The filthy streets, cows wandering around, working camels and water buffalo with carts, donkeys, dogs, open sewers, men pissing on every street corner. It's not for the faint hearted. But it is wonderful, colourful chaos, full of adventure and challenge!
