I had read recently that they're looking for some other alternatives than nodes, which they certainly need because that's a drag. Just a drag, and the fact that my arm is never going to feel the same again. Plus, its a drag to be sure that I am wearing something that reminds people that they can't touch this arm if anything happens to me. Although I have met women in many other countries in the world wearing bracelets, too, which say "Keep Off." So we have a new sorority.
