It's odd that "low Testosterone levels" (as in "lower T levels compared to ...") is automatically considered to be something bad (by male readers). High T-levels are connected with higher susceptibility to inflammation f.x.
that's why I wrote my comment precisely as I did. the article is not about low T levels but comparatively low T levels (comparing to single guys)
uh, yes, a lot of them do. it's just seen as 'normal' to be a lackadaisical limp-wristed fatass "man" these days.
