A co-worker has one of those page-a-day calendars, where you tear off each day and it has some interesting content of some kind… normally, they’re comic strips, or trivia, or word-of-the-day things, but this one is a survival calendar. So it has things like “Today in survival history” and “Today’s Hero” and the best, various survival tips.

Among such choice tips as “How to stop a runaway camel,” “How to escape from a sinking car” and “How to foil an alien abduction” is one that was too good not to share here:

How to Jump from Roof to Roof

1. Look for any obstructions like gutters and small walls at the ledge of the roof.
2. Make certain that you have enough space to land and roll.
3. Check the distance between the buildings.
   Most people cannot jump farther than 10 feet, even at a full run.
4. Run at full speed toward the edge.
   You will need 40 to 60 feet to gain enough speed to clear about 10 feet of distance.
5. Leap.
   Make sure your center of gravity is forward. Try to land on your feet, then immediately tuck your head and tumble sideways onto your shoulders.
