As a medical student, perhaps I can give some recommendations on the best free resources to learn medicine. If you like YouTube videos, Ninja Nerd has a great channel for learning the foundations. If you like textbooks, I used Guyton for physiology and Harrison's is probably the standard for clinical medicine. If you just want to look up how to treat a specific condition, look up "<condition> clinical guidelines". You'll always be missing the additional knowledge that comes from years of experience, but there's no harm in increasing your knowledge as long as you maintain the humility to remember that your knowledge is incomplete.

It's similar to how I learned software development as a hobbyist, so I understand a little about headlines like OpenAI switching from Next to Remix, but at a deeper level, I don't really understand what it's like running Next.js at the scale of MAUs. But it's still worth learning so that I have a little more understanding about the world around me.
