Wow! Thanks Amanda!! I'm amazed! What a kewl idea! Thanks VERY much for sharing that! I wouldn't have thought of it! I'll have to seriously consider that! RonL. (Who (A) also has trouble justifying the cost of an Aeron - but can probably swing a large exercise ball, and (B) sees people having fun using those buggers at the local exercise club but has been kinda afraid of looking waaay to dorky to try it in public, and (C) has a back that has been painful of late, and (D) thinks the fun|wackiness|eccentricity factor is waaaay to high to ignore! Neat!) -----Original Message----- From: A. Erickson [mailto:amanda at gawow.com] I also have a friend who sits at her desk with one of those large, blue exercise balls. She says that her back feels great. I'm considering doing that myself as I can't afford an Aeron (though I do so covet) and I think it would be fun.
