Yes very tragic, also new members should be made that the disorder is a progressive disorder that often leads to a co-morbid affliction CMD which is defined as chainsaw modification disorder. In this progression afflicted persons will attempt to modify or have modified the chainsaws that were acquired in the earlier stages of the disorder.
Initially symptoms are confined to slight hearing loss associated with increased SPL (sound pressure levels) created by muffler mods. After this relatively benign phase toxicological effects are often observed, blood analysis frequently indicated elevated levels of lead and upper respiratory tract irritation. The suspect cause is the use of aviation fuels containing lead and high oil ratios. Respiratory tract irritation is particularly acute in individuals with a sensitivity to castor oils.
Other symptoms may also bee seen at this stage including RSI (repetitive strain injuries), to the hand and wrist areas it is believed these are predominantly caused by hours spent conducting computer searches on chainsaw modification related topics. This is further compounded by the high frequency vibrations of porting tools and ultimately the stress imparted to the wrist tendons when starting high compression chainsaws. Medical practitioners are advised to watch for embedded aluminium and steel particles under the skin of the hands as a sign of advancement in the progression of the disorder.
Later in the progression hearing loss becomes more profound, it is suspected this is a result of adding tuned pipes to the chainsaws which dramatically raised SPL and associated hearing damage. Also blood analysis often reveals elevated levels of metabolized methanol with a suspected source being race fuel.
This is a progressive disorder, however most individuals eventually grow out of it, none the less it can be a debilitating and scarring disorder lasting many years.
