Very sorry to hear about your heart attack. As a registered nurse who works in a cardiac critical care unit, I see every day, just how scary it can be.
I sincerely hope that you can keep your resolve because tobacco does play a very bad part in all that.
And, as a guy who is overweight, smokes cigars, and drinks spirits, I applaud your strength and desire to do the right thing.
I fight in the hopes to show enough moderation and self control to stave off those kind of issues.
Kudos to you on this big step!
And may you enjoy a long life enjoying your loved ones and any other hobby that you choose to replace this with.
