Very well said.
All three of my girls have Onie Jones in their bloodlines. It has never bothered me. Scarlett lived to 19.5, only to get Osteo (so rude at that point!) 2 months before I had to let her go. Morgaine died suddenly of status epilepticus. Knock wood, Aquitaine appears quite healthy except for greyhound teeth.
I was virtually raised in my vets office since my mother and grandmother bred poodles and we showed our until each received their championships. At 6 I fell in love with Danes and my vet told me I was too emotional to get one as they didn't live long lives. He was right, but I still love them.
What I have learned with my girls, and from reading about everyone else's greys, and from dogs in general is that I have to love them every day as if it was their last. Does it s*ck to wake up every morning knowing that "this might be the day", of course it does but it won't deter me. My girls are priceless to me. The love they have given me, and the comfort during some very scary times, is beyond measure. Not one of them is replaceable. That will never stop me from adopting again as the love will just continue to flow through each one of them. If I can only ever adopt one at a time, then I will be a serial adopter.
Panic is pointless (but you don't want to be within hearing distance if my girl gets hurt...I scream VERY loud). Enjoy each day.
