Having read an anti-vaccination article on social media posted by Huffpost, I would like to conclude that whatever things called '' business '' are not really business, not supportive, but business.( I don't understand) They trick us blatantly or nonchalantly and try to make a profit. I tended to be attracted to free products like social media. However, now I think that I want to train my eyes to be able to distinguish what's right and what's wrong so that I can live independently to a certain extent. Well..most things in the world are gray, not black or white. Life is difficult. That may my conclusion to this article. Haha.
