back to the future locomotive

To make a social world before photography, we'd have to make a world without picture IDs; without portraits of ordinary people; one without pictures as souvenirs of travel; one without celebrity pictures; one without advertising photographs; one without X-rays or views of outer space; your global without views of foreign and exotic peoples; one without pictures of sports, wars, and disasters; and something in which the great many people had no way to visually record the important events with their lives. The hard starting problems of diesel engines in below zero / freezing temperatures are generated by two factors. One is the initial cold air being drawn in to the turbocharger and compressed in the engine?s cylinder head. The second is the fuel itself, is also cold and also this sub zero / freezing temperature fuel is sprayed to the cold engine?s combustion chamber, where it mixes while using cold air drawn thru turbocharger. Long before there have been machines to work out on and competitive sports to stay moving and before wars were being fought, man didn't think about conditioning as a way of keeping healthy. He simply knew if he didn't hunt, he wouldn't eat if he didn't run, something would hunt him. They were a down economy that focused simply on survival.
