welcome to Doha 'club'...you said is that Doha is hot than London; just for the records, actual high temperature of 44degC is not yet the highest!! expect more in coming month!! this is just to encourage you!
you said that food is cheap and very tastefully; keep in your mind 2(two) risk factors: a) due the hot weather you can't do jogging outside; b) without jogging you will become fat, as most of local young people!!! you said driving in Doha is crazy: don't worry! here cars are hitting each other, just for the pleasure of their crazy drivers, that's way they are smiling all the time...BTW 80km/h is for some of the limit of MINIMUM speed.....................
