I would never wish diabetes on anyone.
However, after nearly than 15 years with the condition, I can honestly say that it has never held me back and, when you look at people in the public eye with diabetes, you can see that the skies the limit.
I don't believe there is anything anyone can do to avoid getting diabetes but you can manage it when you do and it doesn't have to have a big impact on your life.
There is a big concern about what you have to do when you have diabetes - needles, injections, watching what you eat, ... - but when you think about what it stops you doing, you realise there's not very much (I've just read a thread about becoming a commercial pilot with T1).
Personally, I think diabetes has made me stronger and more determined - as soon as I was told "diabetes should not stop you doing what you want", I was determined to push this and, so far, haven't found anything I can't do.
In the 15 years I've had the condition, I have seen improvements in availability of treatments such as pump, cgm, faster acting insulin, ... - I see this development improving and even if we don't have a cure for someone who gets diabetes aged 2 today, I believe their life will be even better than ours and diabetes will have less of an impact.
