since living in an old victorian house
me and mrs noticed an occasional mysterious smell of rancid fish

for first few years we thought it might have been drains,
or some chemical solvent based damp proofing agent in foudations..

or something even more suspicious decomposing under floor boards..

then recently i realised it occured everytime i changed a lightbulb..

never noticed it anywhere else before..
but the lightbulbs we buy from Tescos stink something rotten
for the 1st few hours they're installed..

why..?????


and they dont last very long either..
