Because that's meaningless. A quantity of blood may be more or less

than a quantity of water. Blood is denser than water, but to say

Stop quibbling, guys.
When anyone says an unspecified amount of one thing is heavier than an
unspecified amount of another, he or she ALWAYS is implying that the
same size or volume of the two things is intended.
Saying the blood is heavier than water ALWAYS is understood to mean
that a given quantity of blood is heavier than the SAME quantity of
water.
Would it be better to be more explicit? Probably, but it is not
supremely important that we be more explicit all the time.
