Had my first MI just after my 39 birthday. That was 18 years ago. Most recent one was April 2020. Have 4 stents and on table for 4 hours have almost 10% of my heart muscle cooked because of AF. Was going into A&E every 4 to 6 weeks with heart rate of 160 +. Still here and only recently stopped work as a high value complex Projects Manager.
Biggest thing to everything is attitude. If you think it's all bad, then it can only go down hill. I have always been a half full sort of person. Take enough drugs every day to choke an elephant. Need new hip and knee which will never happen as I am to high a risk.
Always look up and look forward. If you do you will always find something that will brighten your day and your life.
