It is not very uncommon for ectomorphs often known as "hardgainers" to get frustrated and discouraged whenever they start attempting to put on pounds, and muscles. As an ectomorph your body uses a different list of rules when doing exercises. This is due to the fact our muscles less complicated more understanding of strain and tend to breakdown more quickly, in addition to taking longer to heal. Long before there was machines to sort out on and competitive sports to keep us moving and before wars were being fought, man didn't think about fitness and health as a technique of keeping healthy. He simply knew that if he didn't hunt, he wouldn't eat of course, if he didn't run, something would hunt him. They were challenging times that focused simply on survival. A tighter built home means less outside air infiltrating in the home, which in turn means less oxygen to use for combustion within the furnace. As the furnace burns fuel and oxygen for combustion, it "eats up" the nearby air, which has to be "made up" with fresh air. If air cannot type in the home as quickly anymore, this could cause serious issues. As the surrounding air can be used for combustion, and not substituted for fresh air, a bad pressure in the space can take place. This could create combustion trouble for the furnace, plus consume fresh air for any person inside home.
