Thomas3.20.2010 This is great information, it will help me to explain some things to family as well. Thanks so much for sharing it with me. Laughter is an integral part of my life, I laugh a lot, even under the most trying situations, I just rented a couple of movies for tonight because I felt like I needed to laugh...hope they work. Thank you again, dear Thomas. I will have my CT scan on Thursday, not sure when I will get results. Again, thank you for everything.
