Well the send it out to 10 should tell you it is spam.

That said, I think some awareness of the possibility of a stroke should exist. We ended up getting my father into hospital earlier this year as I (and Pip) thought he had suffered a minor one. His speech was far from coherent and he had some difficulty with one arm for a short time. In that instance, it turned out (through the scans and whatever) not to be a stroke but something called post stroke epilepsy, a late effect of a stroke a few years' earlier. He's now on something called something like Epilim for it.
