Letter in yesterday's Torygraph:
Sir – My husband fathered our first son at 47, when I was 32, a second son at 49 and a daughter at 52. All were healthy babies who have now grown up and produced eight babies between them.
I question the statistics of older fathers causing autism.

Research Results, upon which our valiant Valerie sees fit to trouble the Letter's Editor, also in the Torygraph :
They found that if the father was aged 15 to 29 when a child was born, the risk of autism was six in every 10,000 children. If they were aged 30 to 39, then nine in 10,000 children suffered autism, going up to 32 in 10,000 for fathers aged 40 to 49.
That's 32 children in every 10,000. So your sample of exactly 3 children is, errmmm..., statistically rather unlikely to be relevant.
P-G Prescription: A custard pie should suffice. This would appear to be your common-or-garden, largely harmless moron.
