Being out on your own without someone to protect you all the time can be a very scary thing, which is why I think everyone should invest in some sort of self defense products. I, myself, have a handful of knives and a stun gun from aaa-safetyfirst.com. My roommate has a very nifty key chain where you can flip a switch and it turns into pepper spray. I would like to get some because with pepper spray you don’t have to get close to the person to really get ‘em good, and with knives I worry about the fact that I will have to be within reach to really jab them. They do allow me to feel safe though, and if you’re ever in situations where you don’t feel safe having a similar product on hand really helps!
