If you want the government to pay for your “retirement” then the retirement age is 66. But you can retire literally whenever you want as soon as you have the resources. Which might be in your late 40s or early 50s depending on education, career, and personal goals.
Also keep in mind that “life expectancy” is an average that is reduced by men that die from car accidents, strokes, and whatever else much earlier than 66. The life expectancy of a 60 year old male in the US is 80.
