Do you always go out at night whether for work or fun? Well then, you should start thinking about your safety. There are lots of bad people out in the streets at night and you do not know when they will attack you or something. It is not being negative-thinker or something, but you have to be prepared for whatever happens. 

It is advisable that you consider bringing stun guns with you every time you go out at night. That way, you could easily defend yourself against an attacker. You could just point and shoot the gun towards the torso of the attacker and for sure, he will be left weak and distraught. That will be your queue to run away and ask further help.
