That one-in-twenty time is the time you lose. *shrugs* Not really, but odds are the odds aren't that bad as you think they are. THere are things you can't prep for, and times you'll be caught with your pants down. All you can do then is roll and come up on your feet as best you can.
Edit: My odd, MUST have with item: work gloves.
Yup, and you might want them work gloves to be rubber too. You never know what you might have to handle.
