Jabs to the head are considered safe but they never seem to be there for me. Body jab was there every time against everyone. Also, I started to feel people's stomachs fold around my jab, so I figured it must be doing something. Moving forward while moving my head is something I worked on a lot. Believe it or not, whenever I stood still and tried to defend with only head movement, I wanted to work on developing my pure defense whether I got hit or not. However unrealistic, my ideal fight would be to matrix every punch and then knock the guy out. Still working out the details on that.
