All the experts seem to agree that optimal retirement investment allocation 1) includes some annuitized wealth, and 2) includes delaying social security payments. It doesn't seem like anyone on the board has an annuity, and it seems like everyone is taking their social security payments at 62. I realize that some people here have pensions (which substitute for 1 and 2), but many here do not. Are there some people here with true annuities? Is anyone delaying social security payments? Is there a good explanation for this disconnect between ER practice and theory?
