Was taking a walk around 10:30 PM when some skinny dude approaches me and asks to use my phone. I just keep walking until he pulls a knife on me and he says not to move. Long story short he stole my phone.

Even though he had a knife I still feel like a bit of a pussy for not doing anything to defend myself. He was real skinny, my height, and obviously pretty nervous. In hindsight I probably could've taken a swing on him and ran but in the moment I was worried that his nervousness would turn into him being irrational and stabbing me if I tried to get away.

Anyway, I've reported it to police and I'm trying to go through the process of shutting the phone down so, at the very least, he can't get any personal info from the phone. Not totally sure how all that works through so if anyone has any knowledge on that feel free to let me know. All I know is that the police needed the IMEI number and apparently that can lock down the phone? Not sure (it's an iPhone XR)

Anyway, besides hitting the gym more and starting some type of martial arts training, is there anything I should be doing to not end up in a situation like this again?

I appreciate any input
