An excellent list. My general rule is to stay at least 20 feet back from the precipice. If I may add a couple:

1. never walk behind a car with its backup lights on

2. when climbing a ladder, only move one limb at a time

3. never walk in front of a car that has its engine running

4. wait for traffic to stop before setting a foot in the crosswalk

5. floss every day

6. keep your shoes on when taking off or landing in an airplane (can't run barefoot over burning, torn metal)

7. if you smell smoke in a building, exit immediately. Do not pass Go, do not collect $200

8. take the stairs once in a while in your workplace, as then you'll know where they are when the building fills with smoke

9. wear a life jacket on a small boat, even if you look like a dork. The water ski vests are less klunky
