Twitter is a wonderful place to share ideas, learn quick tidbits, and to get a sense of the 'zeitgeist.'
Unfortunately, many people use it as a platform to share their crazy opinions and famous people are able to propagate all kinds of medically questionable myths (read Hoffman SJ and Tan C in BMJ re: following celebrities' medical advice). The Jenny McCarthy- and Gwyneth Paltrow-types persuade others with obvious contravention of science. However, the subversion of the process of medicine can also be subtle.
BEWARE it may make you shudder to read it:
If you can afford to have your blood tested for everything available, do it quarterly so you have a baseline of your own personal health . . .
a big failing of medicine = we wait till we are sick to have our blood tested and compare the results to “comparable demographics

Fortunately, before Mark Cuban (billionaire entrepreneur) could get too far with his "more is better" evangelism, Charles Ornstein (Pulitzer-Prize winning journalist, @charlesornstein) challenged him. Too bad that challenging people often makes them dig their heels in deeper.
Did the evidence provided sway Cuban? See the play-by-play on Forbes.
