Age 40, if there's any kind of history or you're having any symptoms, or if the doctor recommends it.

My doctor recommended it, and the woman today said due to my depression it would be a good idea to ease my mind. Otherwise I'd have had to pay for one.

I almost feel guilty taking all this help because I'm not as destitute as other people. But I'm under the income cutoff so, dangit, I'm not gonna feel guilty no matter what some other person I used to be involved with who shall remain nameless says about people who accept help.
