Choosing passion or realism

For my older med students with chronic illnesses or physical body restrictions, how did you go about picking a specialty? Looking for any stories or advice about people either settling into something that was less physically demanding or pushing through because they were just so invested in that specialty.

For context, I'm really interested in a surgical specialty, because I love anatomy and using my hands and I don't like the idea of spending most if not all my time in a clinic seeing a patient every 15 minutes based on shadowing experiences. But I'm really worried that the extreme lack of sleep and constant physical demand that happens in residency will either completely take me out, or I will be permanently on meds or in pain because I'm trying so hard to keep up. Is it worth it? Or is there a way to find a specialty that's just good enough, but it'll mean less physical toll?
