Just finished your book and I'm a converted break even analyst. I plan on waiting to age 70 to collect. However, I couldn't find an answer to this question; My wife's earned benefit is less than half what she'll receive as a spousal benefit when I retire at 70. She is a year older than me. Can she start collecting her own benefit at 62 (or 66, 8 mo.) without impacting the spousal benefit she can receive when I start collecting at age 70? I read all about "deeming" but she's can't claim a spousal benefit until I start collecting at age 70, right?
