I would never survive back in the caveman nights, and my body is just too fragile plus weak! I use unscented soap since I get a rash with all the other brands. I have to use sensodyne toothpaste because I get sore teeth plus gums. My greatest weakness is absolutely air quality though, especially when it is dry. Moisture in the air quality makes me sweaty plus after that all of us chop out, however no section is safe on our body from pimples; But the dry indoor air conditions are worse. My body just can’t function if it gets dry. My legs, arms plus chest get dry to the point where I flake skin. My lips crack plus bleed plus chapstick doesn’t repair it, the nose is the worst though. I get bloody noses all Winter long. The inside of it is basically one big sore spot that bleeds when I touch it. To help fight these symptoms I use a humidifier with our furnace. A heating system unit naturally dries out the air quality in a home. A humidifier than introduces moisture back into the house. Not only are our concerns less severe, but the heating system works better. A cabin just feels warmer when there is more moisture. I can set the temperature control a bit lower plus then save some money. Can you imagine me living in the wild? I would be a mess. The dry outdoor air would kill me. My skin would be one dry, rashy mess after a week. I constantly think that the survival of the fittest phrase does not apply to me. I am the extra guy society has saved.
