Hello everyone. I'm new here and I want to start with a question which comes to my mind every now and then. I hope than someone might help me. When was the moment of the most radical expansion of average human lifespan? I know that it's presumably somewhere in the period of industrial revolution and the beginnings of capitalism, but can someone explain it to me more precisely? And - what is actually most important for me - do you know how does the change modified the quality of daily live? Do people really experienced the expansion, do they felt like they really have more time than before or was it only like a shift of scales, barely noticeable? Maybe you know about a book or an article which examines the issue? Thank you all in advance. Best wishes, Kuba
