Thanks, i got it now. Oh, another thing. I was told that even if  i never worked, i could get some benefit from spouse, is that true?
Sure you can. Only need to be 62 and your spouse to be receiving retirement or disability benefits. Also , you can qualify for medicare at 65.
Thank you. A last question. Is there any kind of discount on the benefit i will receive if i'm not in full age of retirement yet?
Yeah. Until you reach full retirement age, your benefit amount will be reduced based n the number of months up to your retirement age.
