I lived through the Blitz for three years before joining the services. "Impact to human life etc" is a bit too much for me to try to answer (in my neighbourhood we just adjusted to it and surprisingly quickly it became a way of life which could be put up with - a lot of people still had clear memory of WW1 and hated Germans which made us somehow comfortable - and we were all certain that we would win). However, if there is some specific detail of which you would like to know I will do my best to answer if I can still remember!
