I viewed the video to a half and found enough difference with what I know that I cannot agree with her conclusions. It is more complicated than performance/longevity. Especially when we going to humans from animals.

For example, reaction speed correlates with longevity: http://www.ncbi.nlm.nih.gov/pubmed/16079205 Reaction speed needs muscle power and neural signal power, both are supported by IGF-1.

Arm grip in midlife is stronger for centenarians: http://www.ncbi.nlm.nih.gov/pubmed/21541735

Thus, while entertaining, the video of your wife is too quick to jump to conclusions.

Why I insist that humans are different.

Number of heart beats per life of regular animal is about 1 billion. Humans average 2 billions. We use different longevity modes than rest of animal kingdom, I think.
