My blue eyed leftie daughter isn't T1, my green eyed rightie son is! Bugger- that blows both of those theories! And SHE had the ear infections as a baby/toddler, HE had chest infections, so that has blown that theory too.
Leftie's are taking over the world though I have noticed from my involvement with young children. That, or I attract them!!
Back to the original thread, I have to say that with the amount of other things that are tested on annual reviews at least T1s have regular checks for cholesterol, BP, etc etc, so actually have other problems picked up along the way.
I rarely visit the doctor and truly can't remember the last time he checked my BP, and my cholesterol was last checked 10 years ago, so I could potentially be sitting on a timebomb. At least my son will have things like that picked up and dealt with.
