I'm 6 feet tall and weigh more than most of you. I'm a lower level "MIT" (manatee in training- the kind without the psycho-ness and bitchy-ness).
Seriously, though.. There needs to be more self defense classes. I keep my head up, when walking around, have my keys out, etc. Like Pickle, I have a knife in my diaper bag (I really do!). I grew up in a tiny town in SE Iowa, (and went to college in central Iowa) so I never had to worry about it. It wasn't until we moved to JAX (the first time, in 2004) and we lived in the scary ass apartments just to the north of the flight line (yeah, you know where), that I had to worry about it.
I knew basically nothing about self-defense then and spent a lot of time alone, with Pickle at VP30 and then as a nugget. Luckily, at that time, I had a "2D" security system. Killian (my 80# Weimaraner) and Guinness (my 95# black Belgian Shepard) were enough to keep most people away. I don't have Guinness anymore, but Killian still raises a hell of a racket.
I can ear-twitch with the best of them, and I am sooo not above kicking a dude in the balls and then getting them in the Adam's Apple with my knuckles.
