Why would I care? If being part of a team effort is what someone desires to tie their life to that's their business. Outside of my relationship with my wife I've never had that compulsion.

I'll have to admit I haven't actually heard the term no I in team used since I was involved in high school sports. I do know the concept was and is employed at lower supervisory levels in the business community, team sports and the military to inspire individuals to function as group effort where individual efforts most often hamper operational goals. But as a way of life? That seems rather extreme unless that's one's comfort zone and choice of peer group, which is the goal of repetitious training.
