You deserve his kindness and generosity. Why not? Everyone deserves competent, compassionate healthcare. The fact that so many have to go without this is a problem with the system. I'm sure you're a good person, but that shouldn't be the point.

Anyway, if you're not doing it already, I'm sure that at some point you'll pay it forward when you're in a position to help someone who needs you. I have no doubt that your pdoc got many lucky breaks and much support along the way that allowed him to get as far as he has and he is now paying it forward with his kindness to you.
