The British team under Simon Baron-Cohen, looking
strenuously in many places and ways, now found a
prevalence of 'Autism Spectrum Disorders' 1 in 100 !

the question is - how many of these are the 'old-style'
more severe cases, and how many the subtler forms ?
or is just the boundary moving, correctly recognized ?

The Soviet tower - the tallest tower in the world !
The Soviet mammoth - the tallest mammoth in the world !!
The Soviet dwarf - the tallest dwarf in the world !!!]

Thank you for thinking about this,
