there are diff degrees of flat footedness if im not wrong, and
for the most severe case where the persons footprint is practically
the whole foot, they r usually downgraded cos they canot run.
some other common downgrade cases would be curved spine, heart
murmur, and blood in urine (i think).
anyway the trick to the balancing log is to walk quickly. i always
haf this fear of falling off it but heng tt never happened!
