social security summary

A few weeks ago my husband received a letter in the mail from the Social Security Services it was a yearly letter summarizing about his contribution to them. Most workers receive this type of letter every year. It said that if he retires at age 62 and if he retires at 65 how much he will get for his pension but he is not old enough yet. It also says how much he would receive form social security disability Pension if he becomes disabled and is unable to work. The money from his summary would not be enough for us to live so he still needs to work for as many years to put more money in his pension.
