But in reality even if you knew you were genetically predisoposed to
this or that, what difference would that make?
I don't know the extent of a connection or not, but it seems right to
me to avoid potentially negative genetic predispositions. Over his
adult life my father had four hernia operations. As I have the same
musculature design, I resolved to avoid such a condition. So I have
for decades done stomach strengthening exercises, no big thing, just
simple stuff. I have also been careful about stretching and pulling
when off balance. I have never had a hernia.
