Well, I don’t want to visit the dentist… does that count?
Joking aside, there are several parts of the world that don’t appeal, due to their political unrest, and several that don’t appeal due to the climate. I have no desire to visit Antarctica, nor do I wish to visit the North Pole. I am not a fan of the cold, so those places are an absolute nope from me. Russia doesn’t appeal for various reasons, and the weather happens to be one of them. The other extreme, of the Sahara, is also a hard pass.
Whilst it would be fascinating to take a look around countries like North Korea, the brutal regime there, and the poverty it inflicts upon its people, leads me to not want to visit. For similar reasons, places like Iran are off the table. I have no desire to visit a country run by a despotic government (of course, given what the Tories are like, I should consider fleeing the UK!).
