For the second time in as many months, I've got bronchitis. Never had it in the UK, but get it quite often here, along with similar eg pleurisy. I wondered if it's the stuff they spray on the fields? When I clean the terraces & garden furniture, there's always a red deposit which has to be power washed off - ordinary hose pressure not enough. That can't be good for the chest, surely? Anyone else get the same?
