That's funny Maia. I love working with aluminum. Many of my projects see me sawing and filing tubes andstruts of the stuff. At work not so much. I've wondered it was bad for me but I do not think in terms of bodily issues as a primary focus. I believe this is what keeps me safe. I do what feels right. Not to say I am right only that this seems to work for me. Especially in terms of such diseases. I know I will never get alzheimers or parkinsons or any other debilitating illness because that is not my lessons here on earth this time around. My mind is a steel trap.
