questions for physicians/dentists

I have an interesting course one night a week – Intro to Medical and Dental Practices. Each week a local physician, surgeon, or dentist comes and talks about his/her experience, gives advice, answers questions. I have loved every minute of it.
I have the usual questions about their likes/dislikes, satisfaction in their field, reality of their schedule, impact on their family/personal life, third-party pay issues, where they think their field is headed, etc.
This sounds silly – but are there other questions I should be asking?! With where you are now - either medical student or physician - what would YOU be wanting to ask? I feel like I’m missing some important information because I’m not asking the right questions.
Suggestions, please!

I’d be networking for some shadowing experiences.
