“At an age when people could historically retire and get full social security benefits…”

Wrong. Very wrong. 

Few retirees claiming today would be eligible for full benefits.

This is poor reporting and is sadly misleading. Hopefully, none of your readers tempted by the clickbait headline rely on this story. 

Bottom line: smart retirees wait until 70 for numerous reasons you should have described.
