It is quite remarkable that church is one of the most dangerous places
for any person with any chemical sensitivity, most often the old dears
and everyone else "plaster"themselves with their most potent chemical
perfumes and antiperspirants so that virtually any church congregation
resembles a group of people in an entirely contaminated cloud of
chemical pollution. This is much more prevalent in a church than any
other normal gathering of people.
There is only one solution, avoid chemical fumes at any cost, give the
place a big miss! Try worshipping open spaces in them.
