Here's the original question:

I'm in the late stages of my college career and wanted to know how much money I would need in my bank account to be financially stable for the rest of my life without any other source of income. Obviously this depends upon my lifestyle and current age, so feel free to make liberal assumptions with either.

I've been wanting to know because I have no real concept of money beyond a few thousand dollars. I feel this would give me a grounding for things like job salaries or just general financial well-being.

Thanks
