Cliff can you tell us more about the stoves and how they are used?

Lacking instruments to measure pollution (other than carbon monoxide
monitors in some homes) its only visual evidence like you witnessed
that we can relate changes to. In UK pub ceilings were stained yellow
from tobacco smoke, nowadays one does not see this similarly in
peoples homes the decoration was stained but most people do not smoke
in their homes now, in fact smokers now account for only 20% of the
population.
