I went to a pre-application talk at Newcastle uni with a friend who wanted to do medicine, and the man doing the talk said that you should never write in a personal statement for med that you had a relative that was ill and you saw the medical care they got, and you want to do the same. Oh and he also said that you should never say that you want to follow in your mother/father/brother's footsteps, or that you yourself have been ill and you want to give back, and he also said you shouldn't say you like Holby City lol. I don't know if this is just what the people at Newcastle don't like, but I hope I helped in some way.
