We live longer because the recent advances in medical sciences has enabled us to.
Also, we are more aware of dangerous substances than in the past - asbestos, cigarette smoking, exhaust fumes, CO2, smog etc.
Also, most of us eat fresher and healthier food than in the past.
Nothing to do with decline of heavy industry, in fact quite the opposite - because of heavy industry people were slimmer and fitter than today. The only difference in heavy industry these days is that we have very strict health and safety rules and much less pollution than in the past.
There were was other factors that prevented people from living longer in the past... And wars didn't help either. |
