I was born in Karachi. It’s currently in the #7 position as one of the worst cities in the world to live in. Right behind Tripoli. I live in Toronto - it’s number 4 as one of the best.
I left Karachi as a baby and it became a shithole according to this study. I moved to Toronto 10 years ago. It became more awesome.
Coincidence? Probably, but I won’t let that get me off my high horse.
