Can husband 61 take early retirement and wife also 61 wait until 70 to take her full retirement if she worked her whole life too.
You sure can - if you have other sources of money to live from during the time.
Note that there may be better options, though. If both wait till 70, they get nothing from SS inbetween.
If the one with the lower expected SS income takes it now, he/she will get it for the next nine years (till being 70), and then he/she can switch to getting half of the spouses higher income. The total is nearly always higher than when both wait till 70.
