OMG (as the kids say), I loved this chat with Dr. Alex; maybe my favourite so far. We did a deep dive on how consciousness is ‘switched off' under general anaesthetic, how to remove a large benign brain tumour (just in case you need to), the amazing hi-tech tools surgeons get to play (work) with, creating the perfect environment for a surgeon to perform optimally (it's complicated), how our brain floats in salt water (and why), why colours aren't 'real', why laughter might actually be a stress response and lots more. Enjoy.
