i was a soft core smoker , smoked about 5-6 cigs a day.. But all changed 5 years back. All of a sudden i realized that smoking is not fun anymore, not sure what has gotten into me , but I luckily stopped smoking that day and my lungs (as per various researches) should be okish now.. Smoking Kills..
