listening to my body

lately, I could not finish a stick of cigar. couple of puffs then I'm done. It's like, there's an inner pull from my body that tells me "hey I couldn't finish a stick anymore please stop" - I do not ignore that voice with in me. So it's smart to listen to my body what it tells me, because it could be that my lungs are weak already and it's giving me a warning that i should lessen my nico intake really soon.
