I'm 44, and I've had two. Such fun! But I do feel a little mixed, and I am really not pro-screening for the reasons they just upped the recommended age to 50. Having said that, I have a friend who had one in her late 40's (with little or no family history), and it literally saved her life (or we hope, double mastectomy and 3 rounds of chemo later...)

I also find it interesting that, even with all the new drugs and ways of testing for cancer, that survival rates haven't changed much in the last few decades.
