Bill (age 42) and Molly Hickok (age 39), residents of Anchorage, Alaska, recently told you that they have become increasingly worried about their retirement. Bill, a public school teacher, dreams of retiring at 62 so they can travel and visit family. Molly, a self-employed travel consultant, is unsure that their current retirement plan will achieve that goal. She is concerned that the cost of living in Alaska along with their lifestyle have them spending at a level they could not maintain. Although they have a nice income of more than $ 100 comma 000 per year, they got a late start planning for retirement, which is now just 20 years away. Bill has tried to plan for the future by contributing to his 403(b) plan, but he is only investing 6 percent of his income when he could be investing 10 percent.
