i have a staffer, like 30 who is having back trouble. sciatic nerve compression. he is today made to do physiotherapy or surgery if that doesn't work out. i am "scared" because this guy stands most of the time, walks to work and back, does most of his work standing. i on the other hand either sit on my chair slouching for 12 hours at a time and if not there, i sit lounging on the floor and do a reclined L with the most pressure on the small of my back. i am concerned because i have had back trouble for the last decade, usually it was kidney stones but later because of my posture. i hope my back is right but i wouldn't want to subject myself to surgeries. shit.
