    Hi Vincent,

    Thanks for this info. Having two kids turns out to be the magic

    I can't really tell, that's why I'm asking this group.

    Is there anyone out there who has the required authority
    to answer this one?

    If IQs are still going up, it would be rather a deathblow to
    my hypothesis. Well, the trend may yet have to
    set in though.

    Philip.
