I've never smoked, but have had family members who did ... they each have told me that it is the hardest habit they ever had to break and when they were smoking, they hated so much about it! The other thing I've only recently learned is that smokers have a much more difficult time healing (from anything) that with broken bones it makes the healing almost impossible. So let's see ... costs a lot, smells, is unhealthy and makes your body weaker ... not to mention the yellow nails and teeth, the stale stagnating smell that gets into your clothing ... hmmmmmm what did you say you liked about it again????
