It is not weird man loses power in muscle after battle for life. The morst thing is no power in mind, Man can not control hiself to sit down and to concentrate on what they want, meaing muscle power can not be used for certain thing like NIW stuff. On the contrary, woman has her own advantage, especially facing critical moment and tough time.Then woman has signifcant endurance and patience, in which man can not be comparable with girl. So, woman sometimes going ahead may get unexpected outcome. Good luck!
