I just read a decent book on maximizing SS benefits. "Get What's Yours" was the title and it is a 2015 publish date. They heavily advocate to wait -- to maximize payouts. If you live well past 80, you'll be very glad you did.......
Took mine at 62 in 2012. March this year diagnosed with aggressive prostate cancer. I'm a livivor right now, not a survivor, since I still have it. Might not make it to 80 so enjoying things now.
IF I'm around at 80,
maybe I'll kick myself in the butt.
