Self hosp before you leave the table, or have someone else that you trust attack you. Ensure revives are turned off before hand by
checking your settings here. Best way to self hosp is by reducing your life by filling a blood bag, then using the wrong blood bag to hospitalize yourself.
The use of blood bags requires an education to be completed in biology called
"intravenous therapy"; this will unlock the use of blood bags for you.
Also a general recommendation is not to post in the forums about someone mugging you as if bringing it to light will encourage them to stop. A lot of players in this game thrive off the suffering of others to the point that Torn actually encourages it. Learn the mechanics and beat the muggers at their own game.
Lastly, remember the human. If you talk big at the poker table, people will remember it and will treat you with the same amount of respect. I've learned about this here recently first hand. Understand there's a whole game around the casino, and that poker is not the primary content in the game. <3
Have a swell day.
