I advise people on this for a living and giving you advise based on what you've mentioned would be malpractice. Like drilling your teeth without X-rays or surgery without an MRI.
Statistically the average man approaching SS age will live into the early 80s. So the average man will be ahead waiting. Without knowing your health and family history can't say how your odds change.
taking the benefits earlier locks in lower annual adjustments not only your base benefits.
As an advisor I would want to know what you would live on if you don't take SS benefits early? What return can you expect? Each year you delay you get a guaranteed return on your SS. can you say that for your current investments or a specific portion of them.?
I suggest sitting down with an advisor. Someone may be giving SS seminars in your area. Yes some of these people will be selling something, but a good advisor will be helpful.
Good luck
