Finally, for those intrigued by this general study, there are further experiments that
are available, other than using your own favorite dog. One might do a similar experiment

one might test to determine whether the optimal path is found by six-year-old
children, junior high aged pupils, or college students. For the sake of their pride, it
might be best not to include professors in the study
