My brother Bill died last week at the age of 82. He had a long, full life and only in recent years developed a severe liver condition which ended his life. His obituary is posted here.
He started sailing early in life and was instrumental in my starting to sail and then buying a sailboat in the early 70's. He was an avid geographer, teacher and traveller.
He had NASH - non-alcoholic steato-hepatitis which leads to liver failure. This is an uncommon disease but is related to "fatty liver" which is very common in our society, which tends to overeat carbohydrates. There is no good conventional treatment for NASH except reduce carbs.
He will be missed by many people and dearly remembered.
