Is weight really that important?

I ran across an article today and it was so crazy, I had to post it on here. Click here to read it. Now I am one of those people that weighs themselves every day but there is no way I'd want my toilet seat to include a scale. Especially one nicknamed "Light Girl"! Sounds kind of super-heroinish. Plus how on earth would it work? Does it continually weigh you the entire time you're sitting or do you have to get up when you're done, let it reset, and then sit back down again? Would anyone really want to buy this?
