text: Since turibles are much less in use these days, it would appear this condition has life-long lasting effects from early exposure to incense. The open question, in my mind is whether the disease is triggered by all incense or just the generally horrible stuff  the one used to find used in the Catholic Church? I hypothesis that quality incense is innocent. and it may even be the quality incense is very less objectionable to those who are aroma challenged. 
  
  Further research is required.
