Mid Life Crisis...MEN

OK, so here goes.  Why is it that when women have a mid life crisis we get depressed and get on meds, but when men do it they just get STUPID!  My hubby is going through one right now and he tells me this morning that he thinks he thinks he will still be with me when he figures out what is making him unhappy.  Why can't men just own up to it, go to therapy, get some prozac and move on?  They become this tornado that will not stop!
