Post Cabg 9 Years

I am 61 don't smoke, exercise, family is full of heart disease. Had my first MI on Nov.1999, stent was put in place and two months later stent failed.

I had a second MI and Cabg that same week. My BP is 132/70 and I live on a ranch where I work cutting and splitting wood tend sheep etc. I have not had a single problem post surgery and feel great. My Dr. retired and new Dr. is just getting started out of school.

Question: I know ten years is a magic number and I am unsure what if anything I should prepare for? I am greatful for the nine years the surgeons have given me but also selfish enough to want to stay around as long as possible. Is the possibility of another Cabg in my future? I know I should take it one day at a time but I don't want to overlook any options available.
