I wanted to add that these are good defensive techniques and similar to driving defensively.

It takes a little thinking and practice. (Riding a motorcycle will make you a better 'cage' driver BTW)

It seems like paranoia, and a lot of work at first. In fact, your first few days, if you really try to adapt a defensive posture, will make you extra tired.

But continue to do it. It becomes second nature and less difficult or at least requires a lot less effort.

I am not a self defense expert but speak from how I conducted myself during Army training and overseas deployments.
