     1        nurse your own children than it is to feed them with a
     2        bottle; is that right?
     3        A.  Right.
     4
     5   Q.   That is not diet related either; is it?
     6        A.  It depends on what one -- a mother's milk is certainly
     7        diet, so the infant -----
     8
     9   Q.   I am talking about the benefit for the mother, not the
    10        child.
    11        A.  For the mother?  Right, I think that is apparent.
    12
    13   Q.   Also, it would appear -- I am not asking you to classify
    14        these in order of magnitude at the moment -- it would
    15        appear that the longer the child is breast fed, the greater
    16        the reduction in risk for the mother; is that right?
    17        A.  Yes, that is what the data tend to show.  But I suspect
    18        there are some limits on that one, too.
    19
    20   Q.   What about the consumption of oral contraceptives as a risk
    21        factor?
    22        A.  Yes -- a modest, very modest effect.  It creates a very
    23        modest risk.
    24
    25   Q.   Again, except in the most ludicrously literal sense, that
    26        is not a dietary consideration, is it?
    27        A.  Right.
    28
    29   Q.   The majority of those things that I have mentioned --
    30        I have not of course mentioned all the things such as body
    31        mass index, height, if you like -- but the majority of
    32        those things are related to social, and not dietary,
    33        considerations, are they not?
    34        A.  Related to -- I am sorry?
    35
    36   Q.   Social, rather than dietary considerations?
    37        A.  Yes.
    38
    39   Q.   When you did your China study -- and I apologise for having
    40        to ask you this, because I have not had the opportunity of
    41        reading that fat book which you brought with you -- did you
    42        measure all these various things: the amount people smoked,
    43        the amount they drank, when they had their first children,
    44        how many children they had, and so on and so forth?
    45        A.  Every one of them.
    46
    47   Q.   Every one of them.  Are all the data available to us in
    48        published form?
    49        A.  Yes, because that book is -----
    50 
    51   Q.   Is it possible to -- I had a quick glance at your smoking 
    52        data, for example. 
    53        A.  Yes.
    54
    55   Q.   Is it possible for lawyers -- who, in your field, are
    56        laymen -- is it possible for us to interpret those data
    57        without the help of an analysis?
    58        A.  Rather broadly and somewhat superficially, yes.  Those
    59        data that are in that book there, are presenting basically
    60        what we call univeric correlations or associations and
