to be fair as a dev there is back pain limbs problems headaches and sometimes unhealthy diet so yeah just because you are setting on your ass all day doesn't mean easy job that alone is a problem in the long run most IT guys i know inclduing myself started that thing in the middle schoolI will always find it curious how there are so many developers with so many health problems, it's almost like mangakas who put their manga on hiatus, the excuse is always that they have some health problem, it's something quite curious to be honest
