Dear Hippocrates,
If you can here me out there, I need you to wake up from your grave and come get a taste of modern day medical training. We actually use something called text-books these days, no more one page scrolls. Feel free to do us the honors of taking USMLE step 1 while you are here, and I must warn you that there is stuff called Immunology, genetics, pharmacology and pathology on this test, which might come as a shock to you, being as your entire medical knowledge comprises of 7 diseases and 1 anti-biotic.
Another thing that might shock the hell out of you is that you cannot do that whole "free" medical service thing you used to do without what we call malpractice insurance, which costs money. Also, don't think that just because you are Hippocrates and offering free service, that you will not get sued. If you make a mistake, it's your ass, and by 'ass', I mean it in every sense of the word, as some mistakes could actually land you in jail where funny things could happen to your ass. I am not going to talk about residency which I will like to leave as a pleasant surprise.
Now, when you are done, you can take your oath back to your grave and I don't ever want to hear from you or the hypnotized zombies your oath has produced.
