I never really had problems with my height (5'6) in daily life. However for me being shorter has made me more fearful and intimidated. I am not an agressive person but sometimes I feel quite defenseless, especially when I see a bunch of 6'5 + guys walking around.
I don't carry knives or guns.
I believe that as a man you should be able to defend yourself against most people. If you are of an average height that is the case. A 5'11 person can fight a 6'7 person, but a 5'6 one cannot, unless he is some kind of world class martial artist or something I guess.
So the depressing thing about it is that you are essentially defenseless against a signitificant portion of the population. I have never had to confront this kind of situation, but I guess if I am faced with a 6'5 + person my only option is to run...
Then again I am considering arming myself...
