I don't think there is much you can do. Based on what you have written, I would assume you already invest a good portion in 401K, index funds, and other options. If you have savings which aren't counted in that, you are better than 90% of the people out there who are happy and chugging along. I would recommend building document with your backup plans and runaway. That should give you ample time to reflect.
