     1        A.  No, but I do know that exercise is -----

     3   Q.   That is a bit lighthearted.  These are quite serious
     4        considerations, are they not, Professor Campbell, when one
     5        is looking at the possible causes of degenerative disease
     6        via, perhaps, the route of obesity or high serum
     7        cholesterol level?
     8        A.  I do not know that exercise promotes a lowering of
     9        total cholesterol.  It may, in fact, actually increase the
    10        amount of so-called good cholesterol; there is some
    11        evidence of that.  But I draw my conclusions on exercise,
    12        primarily on the basis of a large number of studies that
    13        have specifically isolated the effect of exercise compared
    14        to diet.  Exercise is certainly helpful; there is no
    15        question about that.  There is some modest reduction of
    16        cancer risk, particularly of cancer of the colon; but with
    17        the other cancers, I am not sure that this much has been
    18        shown.

    20   MR. JUSTICE BELL:  Shall we break off?
    21
    22   MR. RAMPTON:  My Lord, yes.

    25
    26   MR. RAMPTON:  Professor Campbell, I hope you have open in front
    27        of you your paper about the Chinese project, the 1994
    28        paper.  Have you?
    29        A.  Yes, I do.
    30
    31   Q.   Could I ask you to look at the bottom of the right-hand
    32        column on the second page, which is page 1154S?
    33        A.  Yes.
    34
    35   Q.   It is not a complete paragraph; it is the one which begins
    36        "Junshi Chen".  Do you see that one?
    37        A.  Yes, I do.
    38
    39   Q.   I will not read it out.  I am sure you are very familiar
    40        with it, anyway.  But am I right that what, in fact, you
    41        did, at that stage at least, was to measure diet as at
    42        1983/84 ---
    43        A.  Yes.
    44
    45   Q.   -- and make a correlation of those measurements with
    46        mortality rates for 1973 to 1975?
    47        A.  Yes.
    48
    49   Q.   These being degenerative diseases of long to longish
    50        gestation? 
    51        A.  Yes. 
    52 
    53   Q.   In effect, what you have had to assume -- and I am not for
    54        the moment questioning the assumption -- but, in effect,
    55        what you have had to assume is that the diets which were
    56        measured in 1983/84 were similar to, if not the same as,
    57        the diets which were being eaten in the 1950s?
    58        A.  Yes.
    59
    60   Q.   Is that right?
