What fact could probably save your life?

Any kind of fact really like:

Don’t mix bleach and ammonia. Unless your goal is to make poison gas.

so I have to ask, IF I put bleach in the toilet, and someone pees in it, is that poisonous?

Don’t make me angry. You wouldn’t like me when I’m angry.

In the case of an animal attack, you don’t have to be faster than the animal. You just have to be fast than 1 other person.

I just need to catch one of you fast runners before you take off and throw you at the animal attacking as I walk off slowly into the sunset…
