I'm a long way from 72t, but if and when I get there, I won't be paying them to either watch my money, move my money, or figure the numbers. If they figure it for free I'd probably appreciate the double checking. The math, as I understand it, is not terribly difficult.
But I'm becoming more of a rabid DIY'er.
"At times the world can seem an unfriendly and sinister place, but believe us when we say there is much more good in it than bad. All you have to do is look hard enough, and what might seem to be a series of unfortunate events, may in fact be the first steps of a journey." Violet Baudelaire.
