I'm guessing the money, of course!! I'm not an anesthesiologist YET, but I plan on being one day, and I know that they get paid excellent salary...about $350,000+. I've heard that some greater anesthesiologists even make more than the president! But there are also the disadvantages about becoming an anesthesiologist. They have a HUGE risk of getting sued by a lot of people, because other people's lives are in your hands for many hourse of surgery, and if you give them too much anesthesia (OR NOT ENOUGH!!) and they don't wake up at all (or DO wake up IN THE MIDDLE OF SURGERY!!), then they could sue, and they could sue for thousands, too. But I guess that's why they earn so much money!! I hope this helps, coming from someone who's not even in college yet!!
