It's amazing how much research goes in too helping others. 
Definitely. The world is an extremely complex thing, and I don't know if we'll ever fully understand it.
Very true! That is why everyone does different things. Very complex to keep it going! I was researching neurofeedback today and it's nice to see how much some doctors care about helping.
I would imagine that people who have certain personality types are typically drawn to becoming doctors. They all seem to be very compassionate! 
Well..I have had some terrible experiences with doctors as have many but there are some who do care about helping.
