Thank you! You have plenty of time to be a grandmother!

The good news is that my little grandson is coming home from the hospital this week. They live very far away from us, so we won't be seeing him again until Christmas.
It sounds like a good idea to ask what type of upper body strength exercise you could do. I do some strength training with weights and also do Yoga. Both are helpful for upper body muscle development. Do you take fish oil? It can help with arthritis, as I’m sure you have read in the Zone books. Since you mentioned are doing the Zone to help your arthritis pain and other health concerns, I’m assuming that you do take fish oil. That’s great that you no longer have the alopecia. Being thin is good, as long as you are careful to eat enough good fats and not go too low in body fat.
You’re lucky to have nutritionists near you who know the Zone. There really aren’t a lot of doctors and nutritionists in the US who are familiar with the Zone. I happen to go to a doctor who knows of the Zone and agrees with that type of diet, though I know much more about the Zone diet than he does. Most doctors here have never even heard of the Zone.
My best to you!
