BTW: (this is an ps. to my post above)I've been doing yoga for a little over a year now. I was very inflexible, etc. and thought I would never get into those crazy postitions.But after the second or third time you do it you notice right away how much further you get into the positions. Yoga seems to set off some hormones that make me giggly, relaxed and energized. I always do it with the shades down and slow music on.There are some specific postitions that are said to help your abdomin, etc. If you are interested, let me know and I can give you more info (books, etc).Andie
