What profession or career would require the most knowledge, not including politics or civil rights activist?

ShaneLer asked:


I’ve wanted to become a doctor, but I want to learn as much as possible and be able to use it for benefits for others, and I mean in the long run. A doctor saves lives, but that doesn’t really help humanity as a whole 100 years from now. What career in life could be pursed that could make you a “Newton” or “Bach” or anyone else that brings ease to others centuries after the departing, and requests a wide arsenal of grey matter? Thanks.

Is cardiac sonography a rewarding career? What are some pros and cons of the career?

GeneBean asked:


I’m interested in cardiac sonography as a new career. I would like something in the health field and think this might be interesting.

If you are a cardiac sonographer, what are the best and worst things about your job. Do you mind working with old or obese people?

Who do you primarily see in this profession (typical patient), and do they treat you well?

Is this job fun? What are the hours like? Are you paid well?

Please, no spam answers. I will report them.

THANK YOU!
