It&#x27;s easy to spend 100 hours when you know there has got to be something to find.
Medicine isn&#x27;t like that. With experience you get a feeling for when you are missing something, and then invest the time to investigate in more detail. I could spend a 100 hours trying to understand why my grandma collapsed in the lounge, but 50% of the time I won&#x27;t find anything at all.
