i have done so many different types of jobs.Aircraft mechanic to Chief, Carpenter to Welder.. The injuries run up and down my body and back. Everyone needs to find there own best work height i need the stool and my feet a ittle higher with the saw just a little lower than my chest so my shoulders dont hurt. In this position i can cut 10 to 12 hours a day and not have any added stress on my body. but like i was saying everyone is different.
