You know that meme that goes, "Don't equate your Google search with my medical degree?" An even better one would be, "Don't equate your Google search with my Google search."
By virtue of their years of training and practice, doctors are much more equipped to handle not only knowing what to search for but also how to recognize reputable sources and evidence-based recommendations. With the amount of shit that doctors have to learn, there's no way for them to keep all of it in their heads. You have to use Google searches to jog your memory as well as keep up with new treatment guidelines.
Pictures really can't do this hike justice. It follows the Bow River, which is a gorgeous blue-green this time of year. Very few people along the trail, which surprised me given how busy Banff is.
