The use of this is very limited. And being as such it meanings are also limited. For example here one is not able or say that fragility of human mind is limited and there all conditions. For a human thought will not be fragile as long as human being are able to think. Fragile can be used and thrice sentences, for example here one can easily say that her heart is fragile while both her ought an action are simmered with fragility. This word could be used for inmate objects like glass. At the same time one here is able to say that a persons skin is very fragile but not the bones. But at a same time one can say that this passing affair was fragile but no one's long.
