I have watched a few medical drama series in my day. One of my favorites is Grey's Anatomy. I love to see that doctors and surgeons are just like the rest of us; deeply flawed.
Some of the procedures you see in these dramas are interesting and it's a great way to understand some of the illnesses people have.
Surprisingly it really helped me when my dad got sick and had to have cardiothoracic surgery. When he described the procedure I had a mental image of what would be involved, as I'd seen numerous Christina Yang operations on Grey's Anatomy. My dad was having his thymus gland removed as it was enlarged (he has Myasthenia Gravis).
I'm not saying every procedure is exactly how they show it, but it is really informative and gives normal people, with no medical background, a chance to see behind the curtain in effect.
