Teenager, if they were inclined.

My daughter when they were children, pierced her younger sisters ears,, took her mind off it by giving her a book to read.

Myself never, though I did succumb by the time I had two children that never slept a full night.

2 to 3 years.

Never.

Smoking, not near children.

Teenage, given that teens go up to 19.

Again, teenagers can legally drink at 18 I believe.
