Hello @mzhp1988, I am sorry to hear of all the heart difficulties you are experiencing. I'm sure that this makes you concerned about your future. As you probably know, @mzhp1988, on Connect we cannot make health evaluations. These type of questions need to be answered in a doctor's office. Your doctor would have the best information to handle these questions, especially about what types of exercise that would be helpful to you with your current heart problems. Will you contact your doctor's office and ask these questions?
Also, congratulations on finding your son after 52 years! How nice that you have an opportunity to get to know him now.
Will you post again and let me know how you are doing?
