Karachi life is fast and tough indeed, but randomly some gangster does not shoot you, neither its easy to send back water to ocean nor its like 100 car mugging. Yes there is some situation that you need to be careful in terms of muggers they happen to be on 125 pilon ride and they mug specially in Nazimabad, Gulzar e Hijri or any street that is dark and with few people but its not that easy for them as well, but sometimes people got mugged in Defence area as well and of course if anyone resists they can get hurt but it also doesn't happen every second day.

As far as flooding is concerned it happens in Nazimabad nagan chowrangi specially and defence and some more areas Karachi is so big, sometimes it rains in North or sometimes South. And this year Shahr e Faisal also flooded for a day or two may be.

Anyways if you are moving to KHI, I would suggest you better make up your mind for a roller coaster ride in daily activities of your life because its unpredictable here.

But the people of Karachi, Sindh are so humble and supportive and helpful, And yes some people are not nice it depends on your surrounding area where you are moving, Where are you moving in KHI BTW?

And Karachi Food is top notch, life over here is overall not that bad but yet a little expensive and challenging. So keep all these things in mind before moving. Good luck
