Just read an article regarding pulmonary issues in MENA region. It makes for frightening possibilities for the future.
The report stated that there are roughly 14 million diagnosed with lung problems in the region but that the total affected could be 60 million. if this is the case then the medical resources will be really stretched and many of the countries just will not be able to cope.
It will not be so bad for the expats amongst these but for the general populace they will really suffer unless massive amounts of money is made available to the various countries medical services.
