I never really thought about my low blink rate freaking people out, but I guess it might.
I would like to add that people should not go to chiropractors for neck or back injuries. If your back or neck hurts see a Doctor of Orthopedics, there is a huge difference in education and in treatment. The AMA resisted chiropractors for a long time, because they do more harm than good. It was only because of politics and money that chiropractors were pulled into the AMA. I have heard too many people tell me that their chiropractor shifted their disk into place or realigned their spine. When you do things like that, it may make things temporarily feel better, but in the long run causes a lot more damage to the cartilage in your spine and it always shifts out again. All spinal movement must be supported by the appropriate muscle reinforcement.
In fact most repetitive movement injury could be eliminated if people would just do some light weight lifting every other day. Our profession tends to be very sendintary, which means we have to focus a lot more on exercise than other active professions. I recommend doing light free hand curls (no machine) using a wrist brace at least twice a week. Doing 100 cruches 3 times a week, will help support your upper torso and assist your spine in holding up your body. I don't recommend doing back extensions, unless you are already fairly fit. Instead pick up a men's fitness magazine and do some of the free weight exercises in there. The important thing is to stay away from machines. Weight machines can be usefull if used correctly, however very few people in a gym, including the trainers know how to use the machines and without someone to watch your form you can seriously hurt yourself. Free weights can be dangerous as well, however if you keep the weight low and slowwwwly do the exercise, you will quickly see the improvement in your posture and reduce your chances of having a repetitve stress injury. Obviously lowering your body fat helps, but I know plenty of overweight, but active and healthy guys, so don't obsess about your weight. Just make sure the muscle under your fat is adequate to support your weight.
