September 15, 2012, was my 67'th diaversary. I was diagnosed in 1945. I have lived this long with type 1 diabetes, and I do not have any diabetes related complications, except some very mild nerve damage.
I don't have any "secret". I do the same things that many type 1 friends have done, but my routine seems to have worked better for me than it has for so many others. The research in Boston is attempting to find why us long term, healthy type 1 diabetics have been so successful. I participated in that research in 2009. The research is ongoing, and began in 2005. There have been almost 800 participants thus far. All of the participants are Joslin medalists who have had type 1 for 50 years, or more.
They have found several interesting things. Many of the medalists are producing small amounts of their own insulin. They have found that we have an inner protection of some sort that keeps us from having problems with our eyes, kidneys and other types of nerve based damage. Our hearts, however, are not protected. Many of the medalists have had heart attacks, bypass surgeries, etc. The Joslin doctors have advised us to be especially careful with our heart health.
