In this argument, author reached a conclusion that to avoid the risk of fracture in older age, a planet supplement of Vitamin D and calcium is necessary. To provide evidence and support the recommendation, author cited the three-year experiment of one group with composed by eighties French women, and shown that according to the suggestion dose, the rate of hip fracture is less than the average level. Although author positively provided one possible way  to bring Gosper to alder people, several vital logic faults left author's argue into a invailiable questioned situation.

First all, author ignore the limit of experiment. According to the result of the experiment described by author, it is plausible to consider a higher amount supplement of vitamin D and calcium may help people who are in the later life to conquer the potential risk of bone fracture. However, the experiment is nothing than a proof that planet vitamin D and calcium is useful in 3 year and only helpful for the candidates who are 80 years old women. Author's solution did not provide any guarantee that the recommendation is available even in 3 year later. Moreover, it is also totally possible that twice supplement treatment only work for French ladies instead of all old people.

Secondly, during the experiment, additional requirement that candidates not only received vitamin D and calcium, but also exercise during that experimental period, might change the circumstance, and thus influence the credibility of the result. I would carious about the usage and purpose of light weightlifting program. In general acknowledge, a good exercise is benefit to people, and strengthen their bone and muscle system, which prevent a potential risk of fracture of bones.

In sum, author used a fault methodology of the experiment to provide evidence of the effect of vitamin D and calcium. I would suspend my decision to believe the treatment for the old people, unless author can provide additional information about the effectiveness for a longer time span and wider people scale. Moreover, a lower rate of hop fractures in the experiment is not because of additional exercise, which is only help the receiving of extra vitamin D and calcium.
