I was 47 when my dad died, he was late 70s, almost 80 but had a lot of health issues, type 1 Diabetes, Rheumatoid Arthritis, I believe he actually died from Peritonitis. We had a difficult relationship he was very irascible and a somewhat over zealous catholic who never really came to terms with my divorce. My mother died when I was 55 eight years later, I treasure those one to one years we had together when she was a widow, I couldn't have asked for a better mother. The last day I saw her we'd just returned from Canada, I was really tired and nearly put off that final day together, so glad I didn't she died the next day of heart failure.
Some people have such a good innings in comparison to others, luck of the draw I guess. Another sad day that resonated with me was when I accompanied my husband round the M 25 to tell my late father in law, my step son had died suddenly, this was something my husband felt he couldn't convey to his father over the phone as he was quite deaf and wouldn't wear his hearing aids, (stubborn) Couldn't help thinking why??? A wonderful young man, husband and father drops dead, from a condition he didn't know he had and a fairly difficult and quite selfish 90 something still going strong
