I tend to believe if possible you should get 1st hand experience to make decision. ex. when i help friends move furniture ,if a heavy items gets moved several Times
Yes....BUT....if you're trying to define your work as simply hard vs torturous, you're going to have to have more examples of moving different furniture, to make that determination. Right?? So, how is it unreasonable to volunteer to have your elbows & knees dislocated??
You could ask football players , that sort of injury is common in Colledge and pro ball.
Not so much Plane. Speaking from experience in the Sports Medicine field, elbow & knee dislocations are pretty rare. More common are shoulder seperations & subluxations. When knees are "blown" it's ususally due to a catastrophic damaging of one if not both of the player's cruciate ligaments, along with one if not both of the collateral ligaments. You could almost call that a dislocation, but technically it isn't until the bones that make up that particular joint are no longer in their correct alignment/position within the joint capsule.
THAT all said, whether its torn knee ligaments or a joint dislocation, it's pretty darn painful, from what I've witnessed, with LONG term rehabilitation required just to simply run again
Now, we just have to get those same players to volunteer for some waterboarding, to compare the misery for Kimba's query
