I think the move on SS is to apply as soon as you are eligible. For me that was 62. I saw an article a few years ago that said you would have to live past 80 to reach the point where waiting to 65 would be an advantage financially.
Medicare is automatic when you turn 65. You will get a form in the mail to complete. I did not sign up for the optional Part B. If you do like it says on the front of the form and tear off the card you will wind up with the additional benefit and an additional cost. Read the forms carefully.
As a disabled veteran, I am exempt from Obamacare and do not need the prescription drug benefit. YMMV

......that’s fine if you plan it that way and are still on a employer plan. But, others should know that if you wait on Part B you can be subject to a 10% penalty for the rest of your premium paying life. Also you give up 24% of your Primary Insurance Amount if you start at 62. Most 62 year olds will live past 80. Better strategy is to look into a file and suspend if your spouse has a PIA, while your benefit will compound at a “risk free” 9.7% next year.
