except the city of kabul and surrounding areas there is no semblence of civilization in afganistan. apart from security threats there are multitude of day to day life problems like access to water and electricity. almost no entertainment options,though u'll get hindi movie cd's and songs, life is tough even in kabul as it is a frequent target of mujaheedin attacks,being the seat of karzai government and american forces HQ, forget about other taliban strongholds like kandhar and whole pak-afgan border.
but if you are young and unmarried with no major worldly responsibility and if the job pays fantabulously..... go for it!! uncertainty & danger is everywhere how long one can hide. go for the sake of adventure, see new different places, do something other than routine and more of the same. life begets you..... take plunge.
