What's your profession? Age?

Just thought after the "how much is your system worth" post that it would be nice to see what all these people do to get $80K systems, and perhaps how long it takes. I'm a 29-year old economist for the gov., just completeed my Ph.D. last month, and my system is at about $10K. Just a pup hoping to keep upgrading...
