Hi najoh, and thanks for sharing your story here in the forums section. You are certainly not alone having started smoking so many years ago in high school. There is nothing quite like 'peer pressure' coercing people to do things they might not normally do on their own.
However, I think that congratulations are in order. The 'congrats' are for you nanjoh! After 40 long years, you have quit smoking!! That is a genuine accomplishment - one you can truly be proud of.
Keep up the good work!
Wishing you well,
