It's not a matter of age. I'm just smart enough not to avoid getting roped into a family before I've had enough fun with tech toys. I'm also smart enough not to drive a brand new car. You can live as cheap as you want to. You just have to know what's most important to you. For me, that's computer stuff.
That aside, a normal house in Parsons runs 50-100K. Cheap housing here folks.
