Breath test with a difference ?!?!

Mooching through the hospital and we came across a lady asking for us to take part in a co test, being a smoker (not proud to admit it too), it seemed a good idea to see what the result would be for interests sake? With the results of a score being 13ppm and 2.08 cohb(%) it's made me stop and take a little think about it all? Maybe time to quit, after all Stoptober is nearly upon us and the weather isn't improving now during the winters now? Allways a good opportunity to do something worth banging a drum about lol
