Thinking about how, in history, you lear about diseases spreading like wild fire in towns and cities. Then I realised that I live in a city.
dense population
Generally dirty
air quality is bad
lack of green space
Fly tipping and litering attracting vermin
you know how when you look in a history book and think 'oh those savages! no wonder the Spanish flu killed so many. look how they lived!' and then realise I live similarly.
in fact my local council is trying to fit even more people in by taking away what little green space is left! We haven't leant have we? I'm afraid we never will.
