Smokers who quit, particularly at young ages, show much lower mortality rates than those who continue smoking.
(Whew! Just made it. I quit when I was 34)
Good for you! I was 37, so I missed the first cut-off ... but still worth it.
It's always worth it, at any age. I quit because I wanted to get pregnant and I didn't want to smoke during my pregnancy/motherhood
@TheoryNumber3 What a coincidence: that's exactly why my husband and I quit as well!
We didn't realized I had conceived at the same time, so I've never been quite sure which were symptoms of withdrawal versus early pregnancy, but I'm glad we stuck with it.
