>If you train to do 180 second one leg stands you aren't like increasing your > survivability. This depends on the exact nature of the correlation between the survival and the "one leg stand up time" (OLSUT). Even if we treat the second as a symptom of some debilitating, death causing disease, say cancer or heart ischemia then it is plausible that with stronger legs one will succumb to such malady a bit later. More likely OLSUT is a more reliable indicator of a physical activity of a person than a questionaries directly asking for it. Unless cornered even alcoholics seldom confess drinking in excess. Sedentary persons probably do not divulge that they have not walk 2km a day in a last year or so. Last but not least, as mentioned by many above: OLSUT can lower the risk of falls. And with 70+ falls -> broken bones -> bed -> pneumonias and/or thrombosis.
