Really sorry to read about your hearing Canio! That sucks, particularly given that you're a music fan. I presume you've looked into other factors like the relationship to diet etc.? My eyesight improved since I changed my diet, so anything's possible
"I think the basic anti-aging diet is also the best diet for prevention and treatment of diabetes, scleroderma, and the various "connective tissue diseases." This would emphasize high protein, low unsaturated fats, low iron, and high antioxidant consumption, with a moderate or low starch consumption.
In practice, this means that a major part of the diet should be milk, cheese, eggs, shellfish, fruits and coconut oil, with vitamin E and salt as the safest supplements."
