Q17 There are those who say, "Even if a healthy person smokes a little,he does not suffer from cancer ." Really? A That's right. "A surprising matter is said in spite of the site which explains prohibition of smoking." There may be those who are amazed so. But, a healthy person's immunity power is excellent. However, to this site, since there is no mind claimed that immunity power is maintainable even if a healthy person continues smoking, please do not have misunderstanding.
