It seems to me he is solving the wrong problem.

The problem isn't that we don't know our fitness data, the problem is that we are lazy and don't want to exercise. We might want to want to exercise (a big difference), but we don't want to exercise.

Solve that problem and you will have a ton of money on your hands.

(I know there are some of you out there who loves to exercise or who do it even when they hate it. Please accept that you are very far from the norm and enjoy your good life.)

I actually think this is a very useful idea.

I'm hoping it goes even further. I'd like my toilet to tell me what is wrong with my diet and if I need to go to a doctor when I'm exhibiting warning signs for some illness (I realize this sort of thing is a little too weird to be a commercial success... but it would be useful.)

Also, as the saying goes, what gets measured gets managed. I imagine if you measured your waist size and body fat percentage every morning after waking up, fewer people would pile on the pounds as their lives get busier and more stressful. Being aware of changes in your body will cause you to think twice before going for that extra helping during dinner.

Stool analysis has been available on advanced Japanese toilets for quite some time:

Nothing's ever too weird. Ten years ago, people were afraid to put their real name on the internet. Standards will shift, as long as customer/user privacy is maintained.

You can already get smart toilet seats that measure some things, like this: http://www.chinadaily.com.cn/world/2010-08/27/content_112112....
