Answering listener questions about retirement investing.

It's striking how well the old rules for managing money hold up. We forget that these insights were forged during scary times, such as the Great Depression of the 1930s and the Great Inflation of the 1970s.

How do you plan your investments when you're planning for people of different ages? If a family has one person who is of retirement age and another who's much younger, how should common investments be allocated? Conservatively (keeping in mind the older person) or aggressively (in the interests of the less old person)? Thanks!!! Rina, Bronx, NY

Having had three job changes, my investments are in three locations, with a fourth about to start. I have a Roth and two 401(k)s. Is it a benefit to combine all investments into one account? I need to educate myself on my money. Most that I have invested is in aggressive funds. I am 47 and getting older each day!! Jeff, Tulsa, OK
