it baffled me how buildings could stay so long in water without sinking.
I have no idea either :D'
How about mosquitoes...?
It is sea water, so there are no mosquitoes around.
How did kids grow up in that area with no playgrounds...?
I have wondered about this too - it would be a strange childhood. I am not sure it would be enjoyable, but if born into it, I guess it would be normal?
