carbon monoxide poisoning

i don't normally blog but i wanted to reach as many people as i could, i usually post on facebook to my friends every year to change there batteries in there smoke and carbon monoxide detectors when they change there clocks forward or back, this year was a little different because a young couple i know came real close to death do to a faulty furnace. It starts a bit like flue symptoms , ache, exhaustion, nausia, . our first response is to go to bed to get some rest, this is were things go bad!! a lot of people dont wake up! fortunately for my friends she got so violently ill they went to the hospital, they very lucky and had a full recovery. i can not stress enough the importance of functioning smoke and carbon monoxide detectors in your homes!!! they are relatively inexspensive and may save the lives of you and your family!!
