I actually have some size and strength (being a rugby player) and I did Karate for a while... but I haven't been in a real fight.
despite coming REALLY close.
So, my advice is to look like you know what your doing, or lok like you could do some damage and they wont even try it. It works for me.
...but if you dont want to go to the gym 3 times a week and start playing rugby with 100KG+ Islander guys... maybe you should try a different course of action.
