Smoking in China and middle age

I found an interesting column by a guy who lives in China and just recently took up smoking in middle age:

After years of resisting, a friend in Shanghai gave me the perfect excuse to start smoking. China has become so polluted, he told me, that it's better to breathe through a cigarette filter than just take in the air on its own. And if your lungs are going to get shot to hell anyway, you might as well enjoy it. So, well into middle age, I figured that it was probably a good time to take up the smoking habit. The result? I enjoy it so much that I don't know why I didn't take it up earlier.

The rest of the column mentions how good some Chinese brands taste.
