Like I said, you need at least 6mo worth of cash or some form of it to make it past life's curve balls. An open line of credit can also get you by the rough spots also, so long as you don't abuse it for frivolous purposes.

I agree about the 6 mos. worth of cash. I'm not so sure about the credit line.
The 6 mos. of cash should cover all expenses. A credit line is a track to disaster. Medical insurance is a better idea than credit.
