Booze + smoking = death

It is reported in a local daily news paper that a person was burnt to death while boozing in his room. It is suspected that he did not put off the lighter/match stick/cigarette due to the intake of huge quantity of liquor and this would have caused fire and death.
Lessons:

1. Do not take liquor.
2. If you have to, do it with others
3. Limit your intake to your capacity, in worst case. 
4. Keep the company of a friend/relation who will not consume liquor at all.
5. Do not smoke.
6. If you have to do it in the presence of a person/relation, who will not take liquor.
