We have an epidemic of bad posture

I'm a tall (1.86 m) and fit middle aged man. I have neck problems from using laptop or bad chair. I started to have lower back problems but I fixed them with a chair.

I realized nearly two years ago that almost all tall people in my office use external monitors and it clicked. The taller you are the worse the laptop ergonomy is. Human head weighs 4.5kg-5kg. If you have to bend your neck even a little bit your muscles have to do lot of static work. You can compensate by bending your back, tall people have to bend their back more.

My hypothesis is that short or fit people can get away more than tall or unfit, but things will show up after 20-30 years of bad posture for everyone.

Or you could (with the right chair and foot rest) angle your seat instead of bending your back.

I don't see how you can fix things with just chair if you work with laptop that is in the table and your are tall.

External monitor and keyboard is must.
