吸烟者主要担心的问题是：如果我戒烟，会降低自己患老年痴呆症的风险吗？
A key question for worried smokers: If I quit, will I lower my risk for dementia?
额外的小贴士：如果你失败了(你们中的绝大多数都会，最少一次)，不要放弃，就像我说的，我尝试了七次才成功戒烟。
Bonus tip: If you fail (and many of you will, at least once), don't give up. As I said, it took me seven tries to successfully quit smoking.
如果我的朋友相信他只能“尽力”戒烟，那他很可能无法成为一个不吸烟者。
There is no try '! "if my friend believes that he'll only try to quit smoking, then he probably won't receive the gift of being a nonsmoker."
