Just to update Tinkobell's information, Bristol used to use personal statements but now selects for interview entirely on UCAT score. Very few medical schools read personal statements before interview (Cardiff and Imperial do; I'm not sure where else), and often only one interviewer on an MMI circuit will even have seen the personal statement.
I agree about the importance of using experiences to demonstrate the applicant's personal attributes and motivation for pursuing medicine, rather than just listing places and dates.
By the way, it's "piqued", not "peaked". Sorry if that was just an autocorrect.
