Know vs. Unknown

I am going to try to pretend I am already a medical doctor. I am going to try to list the knowns and unknowns in my field of study, movement science.

Known

• smoking is bad - causes lung cancer
• eating health, get all the nutrients you need in a correct serving size, will help you be an appropriate weight and have a healthier body
• early diagnosis can help prevent unwanted outcomes
• treatments and medicines change daily so you always have to learn about the new best thing
• have a positive demeanor helps the patients have a positive demeanor
• trying every available option may not be good enough
  
• you can treat almost anything
• sharing information about patients is not good
  

Unknown

• can't cure most terminal diseases - cancer, AIDS, malaria
• why some people get better and some don't
• what is the best medicine/treatment to use
• causes of some diseases
  
• why some treatments work for some and not for others
• whats morally right or wrong

Continuing our topic from class though our fact now was not fact in the past and by the time I am a doctor we have may have figured out that some of the fact now isn't true. Hopefully we may also find truths for the unknown so we can better assist the ill in our community.
