Quitting smoking in your 60s - there is no age limit to stop

Quitting smoking in your 60s can still boost life expectancy

Basically, there is no age limit to stop smoking, yet scientists suggest that kick the habit should not smoke as much as possible or until their 60s. This is because the faster they stop smoking, the longer persons are likely to live. Also, experts find out that all smokers can emphasize smoking cessation, regardless of age. Therefore, although smokers have some opportunities to live longer, they should consider the negative side from smoking especially causes of smoking-related death included lung, heart disease, and respiratory conditions.

I totally agree!! This is a good one. My grandfather quitted smoking at 59 and he is now 78. I can't believe it worked. But apparently, if you quit any time, you are getting back your lungs(unless you smoked real hard in your 20's that your lungs would probably be almost dead now)
