Mommah,

I am truely sorry if you felt offened by what what Butterfly has so aptly described as light hearted banter. We tend to do this from time to time, perhaps to reducce our stress levels?

I do sincerely hope that your questions will be taken seriously, and in view of your profession, you may well be in a better position than others who are diagnosed with PD to have access to more up to date information, which I hope you would care to share with us

With regards

Dear Mommah
it is still a question of mathematics however, With a large population as in England and a fair;y common event (1 in 500) an entirely random distribution will not be even but will have some sizable 'clumps' in it ie some streets will have zero, some will have eight. You might be living on a random clump. Investigators would have to find something other in than the mere occurrence of pd to show it was not random.
