Not really, but your wife' account will need to start withdrawals at 70 and half.
"Since nothing the IRS does is ever simple, knowing when you need to start taking mandatory withdrawals, is but of course tricky. As you approach 70 1/2, you're faced with a choice. You can take your first minimum withdrawal during the year you turn 70 1/2, or you can take it by April 1 of the year after you turn 70 1/2. Then for each subsequent year, you must take at least the required minimum withdrawal by Dec. 31 of that year.
Why does it matter when you start tapping your IRA? Well, it can have significant tax implications. After all, if you don't take your initial minimum withdrawal during the year you turn 70 1/2, you must take two -- and pay the resulting double dip of taxes -- in the following year."
