Am I the only one with a career!?
No, by my reckoning several of us do. I actually voted for all four options. My job is my career, and some of it I like. I'm also a student of life, and I'm in student mode most of the time. I study many problems both formally and informally. I also depend upon my wife's income, which has always been about 75% of mine, but this year, for the first time ever, is exactly the same as mine, and as a matter of mutual agreement we save 100% of my net income each month and use 100% of hers to make a living (rent, food, clothing, vacations, etc.) so technically my son and I are symbionts to her host. (We should probably thank her for working so hard.) To some extent, therefore, all four apply.
