The study data from 2004-2006 is already outdated. In January, 2007, the Environmental Protection Agency, the oil companies and the trucking industry phased in Ultra-Low Sulfur Diesel nationwide as the predominant on-highway diesel fuel, with 15 ppm sulfur. The former fuel, Low Sulfur Diesel, had 500 ppm sulfur and before that, diesel had something like 5,000 ppm sulfur). The next study will tell more, but it will be outdated as soon as it comes out because the 2010 regulations will already be upon us that will include increased idling restrictions (Pennsylvania is one with a pending law), ship and port emissions regs, CAFE standards, etc. There is also hope that all motorists, truckers, commuters, etc., will learn to drive as efficiently as possible and reduce idling, etc. The federal government is going to try to \"solve\" congestion by imposing tolls on motorists to drive in non-congested lanes. This pricing scheme is going to be expensive if we allow it to happen. Drive smarter and know your routes and maybe we can all avoid paying excessive tolls- which is another word for taxes. The government is going to tax everywhere they can in this whole smog/global warming/congestion scenario.

Hey reloader 212, Maybe you live in filth and but I live in a beautiful, scenic section of PITTSBURGH. Spare me the Indian atrocity analogies and raped land analogies. There are more trees in this country, per capita, that there was at the turn of the century in 1900. That's a fact. And I just knew you would find a way to blame it all on Busch. Grow-up. You're clearly unhappy with your country so why don't you just take your ball an go to another home... not on this continent...or universe.

I mean, of course, that children aren't expected to live longer *lives* than their parents, not that they are expected to die before their parents do.
