what is with this "if you m are younger than 70 have it fixed"****? I am now 78 and refuse to give up . Last year November 13 had right shoulder operated on after 3 months of therapy . Cuff torn in 2 places and bicept detached . followed therapy and this month i can finally raise my arm over my head without an assist from the left arm. Kept complaining and they kept telling me it sometime takes a year to get full movement back . I have to admit it was a pain in the arm ,but kept moving and doing all kinds of moving ,little by little it has come back to normal use. It is worth the struggle YES
