I am writing to comment on the weight loss issue. I got the best results using a Richard Simmons thing called “deal a meal.” That was in the 80′s. Now it is a pocket-sized plastic case that you keep with you throughout the day. Every time you eat a serving of a food group, you slide the little plastic door closed on that serving. I have never met Mr. Simmons, but I have e-mailed to thank him. When all is said and done, you learn to live without eating anything at all that is packaged in a “crinkly bag.” That is to say, the things you eat are not very far removed from the way they looked before they were processed. Exercises that can be done in one place that are continuous and involve your whole self are more helpful. Any modern dance floor work video would do. By “modern,” I mean icons like Merce Cunningham.
Good Luck!
