Temperatures of over 30'C (not scientifically qualified with ISO & no Met Office in those days) no refrigeration, impossible to keep food fresh & no functional sewerage system, everything you didn't want ended up in the River Thames, chamber pots, new-fangled flush lavatories, road gutters (surface sewer from the less affluent), decomposing food, industrial waste, incl animal parts from abattoirs & chemicals (slime) from leather tanning factories .......... get the picture & think about the smell ??? In Thames itself drownings & suicides were common & bodies were rarely recovered ........... now do you get the picture & how about the smell now ??? On top of this, everything was horse-drawn - so the streets were full of massive piles of horse sh manure, now imagine the flies swarming on this ............ get the picture smell now ???
I might be happier at my clean & fresh smell free, if slightly humid, 30'C++, braai & afternoon/evening party tomorrow.
