Hi,

Yes, since you were apparently born before January 2 1954, you could claim spousal benefits only when you reach age 66, and allow your own benefit rate to grow until age 70. This is likely the best strategy in your case, however, you may want to consider running the maximization software available on this website in order to be sure.

Best, Jerry
