This is a bit of an odd question but it is something we need to think about when we are planning for retirement. Some people plan to have a lump of money that they intend to draw down in their retirement while others expect their retirement savings to produce a sustainable income for them. In some cultures, it is expected that the parents will live with the children later in life and in others each generation remains separate. Do you plan on living to 80 or 100? How we plan our retirement depends a lot on how long we live. If we expect to retire at 65 and live only to 80, we can draw down our savings. If we want to live to 100, we have to keep our investments growing to keep up with inflation and keep us in cash. When you set your retirement goals, are you planning on 15 years or 40?
