                        Your wife is fortunate not to have been affected until 86 ... I got mine at age 20 and am now 65.  You would think, as common as this abnormality is, that some "Rocket Scientist" out there would have made a discovery and found a cure by now!!    Tell your wife to "hang-in-there" and join the club.    Regards,    DG
