5.1. A couple is told that to retire comfortably they will need to accumulate a nest egg of about $1 million dollars. Is this an insurmountable hurdle?

5.2. What would happen if at age 50 the couple needed to access $100,000 for an unforeseen emergency; how much would need to be saved in the last 15 years (assuming 8% annual return)?
