Hi IME,
Good to see that you are in such good health.
However the parallel you draw between you and the rest of your family makes at best for anecdotal evidence that there is more to the causes of ischaemic heartdisease than Cholesterol and weight.
After all driving down the motorway @ 130 mph does not ensure that you will be dead before you reach your destination; but like smoking Woodbines it makes it a whole lot more likely!
