Yes - it is a convenient excuse to avoid drinking alcoholic drinks, when I am offered them, although I have been a teetotaler all of my life - I'm 66 now.
I have never smoked either. My thinking has been that since I am an Organ Donor, if I die prematurely, i would not want to pass on to the next person, or person's, my organs, which were abused and corrupted by my excesses, in my life.........
I abused myself and my body by eating far too much, not the best diets and lack of exercise and that is basically why I got diabetes, so for me the cure was relatively easy, by changing my diet and cutting down massively in my food intake combined with more exercise, I have been diabetes free these past 4 or 5 years.
Time seems to flash by, the older I get!!!
