The blank forms above are intended to help you create a graph for each domain in your life. The scale on the left, from Very Lo to Very Hi is a measure of quality in your life. You will determine the quality level for each domain at each age. For most people, parents will be responsible for several of these domains during the first 15 to 20 years. You will be most concerned with the trend over the last 10 to 20 years of life, as the direction of the trend line on each graph suggests future possibilities.
To create a graph, make a mark in the box for each age and quality of life rank, then draw a line from the first mark to the last one, as shown in the example. Now, project two lines for the ages in the future stage you plan to study, one for the highest plausible ranks for that stage and another for the lowest plausible ranks.
The resulting extrapolation for each chart should be a cone shape that starts at the present and extends into the future. The area between the upper (optimistic) line and the lower (pessimistic) line is a cone of uncertainty, the area in which you will create your scenarios. Wild card events occur outside the zone of uncertainty.
