Our house is about 150 years old and we dug down to the dirt floor in one of the downstairs rooms. We found suspicious white bits, and had to send a sample off. Luckily it came back clear. It was unlikely anyway, as asbestos wasn't in widespread use here in the 19th century.
However, we do have corrugated asbestos roofing on our "scullery" but it's in one piece so can be left until we renovate that part, then disposed of safely. It's pretty common to find it on sheds and outbuildings here.
I'm trying to think of something I can actually do, but all I can think about are weird coincidences beyond my control:
My parents and my husband's parents were married on the same day in different parts of the country. His dad also shares my birthday.
My first child was born on the same day as a moderately famous comedian's first child. Later, when I looked that comedian up, I realised my second child was born on his 50th birthday.
