Smoking is a tough habit to break, and while there are plenty of deterrents already, this Vine pretty much sums up one of the best reasons why you should do your best to give it up.

We all know that cigarettes will affect your lung capacity, and there are plenty of notices on the packs showing you some pretty grim-looking lungs that are in a bad way. This Vine however, shows exactly what it looks like inside your body when you try and take a deep breath if you're a smoker, and what inhaling all that tobacco is doing to your lungs when compared to a healthy pair.

As if that's not reason enough to give up, the British Lung Council have one more to add: smoking also "affects the reproductive system and sex organs. Men can have difficulty getting an erection and it can reduce sperm count".

Food for thought.
