my mum did everything right too,
after dad died in sept 2002,mum aged 64, I became very involved in her life. she took ginko bilboa, multi vitamins, ate lots of fish, did the daily crossword, did the weekly puzzles in the magazines, etc etc but to no avail...none of it made the slightest bit of difference...went on aricept in 2004
five years on she is in a NH home unable to shower,dress,read ,write,recognise loved ones etc etc
at the tender age of 70
just like the people that dont smoke etc get cancer
its a lottery, and I am a smoker
To quote you "what will be will be"
Hope you have a nice trip,
