Can't quit smoking or drinking?

I can't quit smoking and drinking, and I will live 20 years less!

In fact, smoking and drinking are harmful to health, which is almost the unanimous conclusion of experts and doctors. However, there are always some old people in life who have these two hobbies. It seems that alcohol and tobacco are their inseparable hobbies and have little effect on their health. Even if they live over 100 years old, people often hear arguments about alcohol, tobacco and longevity. Today, we will look at Grandma Jiao. She is 105 years old. She used to smoke and drink for more than 50 years, and then gave up smoking and drinking for more than 20 years.
