You will receive the same monthly Social Security benefits (adjusted for inflation) no matter what age you start collecting.
Survivors can collect Social Security benefits based on their deceased spouse’s work history and earnings once they reach age 70½, even if they have no children.
You can receive Social Security benefits based on your ex-spouse’s work history if your marriage lasted at least 10 years and if you never remarried.
Once you start collecting Social Security benefits, your payments are adjusted for inflation only after age 70 (because that is considered the full retirement age by the federal government).
The government requires that you take Social Security benefits as soon as you stop working (full-time) completely.
