elevator 1234* michael bloomburg has escalated his war on fat people to include a campaign encouraging everyone to use the stairs. under legislation proposed by the mayor all new buildings would be required to increase the visibility and access to staircases because as one official noted in most places they are too dark and scary. so what does bloomy think of his health initiatives ? >> nobody is going to tell you how to live, but all of these things no matter how much you want -- some people want to make fun of them, these are things the results of which you can see and that new yorkers are living close to three years more than the national average. we must be doing something right. >> what is that about that voice? is walking really worth it? a 150-pound person must climb stairs for six hours and 30 minutes to burn a single pound of fat. to lose two pounds you need to throw up while doing it. old habits are hard to breakment breakment -- are hard to break.
