Lydia, who's love of job shines through....
I just skimmed what she read, as she did have kind of a "superior" tone to her voice, didn't' she. But how superior can anyone be that suggests walking down a staircase backward without holding on, right? ~ now I'm going to have to go back and actually read what she said. :?:
I pretty much just looked at the various tests, thought the stairs were ridiculous, but could be modified to be helpful, and the driving was not realistic, it would depend on degree of weakness. Never thought much about the jump rope as I wasn't going to try it either.
However, it is an idea, like Beth said, if those so inclined, that really want to know if they are able to maintain, build. or get weaker, to work out their own routine. It could either serve to calm fears, or, be able to confirm that something is amiss.
I do think that those who are in touch with their body, those that regularly work out, do yoga, whatever, or have a physical job, are going to be able to tell if something is off, before someone with a focus elsewhere.
