I did. Uncles and aunts ages at death:
72, 77, 76......
Now if you start collecting at 70 and only live another 5 years, how much did you collect? Approximately 78000 dollars...its pretty close.
And no guarantee when you will die.
I work out 6 days, regular check ups, watch my diet but tend to over eat at times. I don't drink.
I was born in 62(cannot brag about that anymore LOL) and when I was growing up, I saved for retirement as if SS did not exist. I do not have to rely on SS to have a great retirement. I will never be a burden to society.
SS is designed not to pay out as much as you pay in.
If you collect at 62 with a life expectancy of 15 years at 75% then you can weigh that against collecting at 66 with a life expectancy of 11 years at 100%.
Personally my dad died younger than the American average and that drove my decision. I hope you live long past you aunts and uncles and enjoy your SS to the max.
