Your body bounces back

The first few days – even the first few minutes – after you stop smoking bring about dramatic results. Here are just a few of the changes, according to the American cancer society and the centers for disease control and prevention.
AFTER
20 MINUTES: Blood pressure, pulse and carbon monoxide levels drop to normal.
48 HOURS: The ability to smell and taste is enhanced. Nerve endings start to re-grow.
2 TO 12 WEEKS: Circulation improves, walking becomes easier, and lung function increases up to 30 percent.
1 TO 9 MONTHS: Coughing, sinus congestion, fatigue and shortness of breath decrease. Cilia function returns in the lungs to help combat infection. Energy level increases.
1 YEAR: Risk of heart disease is half that of a smoker.
5 YEARS: Risk of lung disease is half that of a smoker.
Even if you fall off the tobacco wagon, exercise lowers a smoker's risk of cardiac-related death by up to 40 percent.
15 YEARS: Mortality rate equals that of a non-smoker.
