square heart ??

[muawiyah]

A "square heart" is simply one where all four chambers are of roughly equal size ~ you can inherit the condition (very common in the Far North among the Polar Peoples) or you can engage in very long term heavy exercise ~ running marathons is a good way to find out.

The "square heart" pumps more blood faster to the lungs, and also adds to the general strength of the heart thereby improving flow to the arms, legs, etc.

It gives you a decided advantage in Cross Country Skiing.
