Going back and forth to London is not a problem for me, as my brother is a pilot so I will get free airline tickets.
I don't really care what people think at university, rather what concerns me is if I get this operation done I will probably will be unable to eat for a while. Hence, I will lose a **** load of weight (I am a slim guy as it is). It's just not a good idea in that respect, as I have suffered from the mumps already, and it was absolutely dreadful because I was unable to eat properly at university (ended up in hospital with drips).
