What would be a better 'life changing event'?

<p>I have two “life changing events” that I’m planning on writing about. The first is that I was involved in a pretty bad car accident last year, in which my car was completely totaled and I’d write about what I learned and how that event changed me personally. The second would be about how my father has gone through two major surgeries and how they drove me towards my path to eventually practice medicine one day.</p>

<p>Which one of these seems like a better topic to write about for competitive schools (HYPSM-level)?</p>
