Without bones, muscles, and joints, we couldn't stand, walk, run, or even sit. The musculoskeletal system supports our bodies, protects our organs from injury, and enables movement.
What do computer programmers do on a typical day?   A computer programmer's typical day will include checking the current list of assigned defects and enhancements, performing code changes, reviewing code changes of peer â¦or junior developers, and perform limited tests of code that they or their team has changed.
But using the computer too long each day (or other repetetive arm/hand usage), probably is the main cause. Look out when using laptops: they have poor ergonomics. A desktop computer is much better. Dutch ergonomists say (regulation): a laptop shouldn't be used more than two hours a day.
