When someone quits smoking, they improve their health and the health of those around them.
a. true
b. false

They definitely improve their health, and since they won't cause anybody to commit passive smoking I suppose they'd improve the health of those around them.

If they have emphysema or bronchitis already, quitting will reduce the effect it has on them (emphysema is a disease of the alveoli, bronchitis of the bronchae). The carbon monoxide in the smoke also would no longer bind with hemoglobin in their blood to form carboxyhemoglobin, wasting oxygen that could be used for respiration, so they get more tired easily etc.

Ithink the correct answer would be that since the disease is passed by a hand shake and can be cured with antibiotics that it could be an infection. an example could be that once when i was working in a bush camp, i got blood poisoning from blood blisters that got infected. our cook did not wash his hands after going to the bathroom and he passed staphyloccus on to the crew he fed. one other person also got a bad similar infection on the side of his face. i had to be rescued by helicopter and taken to the hospital so i wouldn't die!
