There are too many people with false confidence thinking they can handle their own in a physical altercation.
Go to your local gym and stress test yourself in live sparring. None of that cardio boxing, or technical sparring, legitimate striking and grappling.
Many should feel the weight of combat in a controlled environment so they know their bodies capabilities.
A lot of delusional people don't know the cardio and technical skills required to hold your own.
911 won't always be there on time, some agencies take hours to respond and that's if they show up..
Stay paranoid.
