I think ide rather just have the flue for a few days, and fight it off naturully.
Edit-
Ive never gottena flu vaccination in my entire life, and the worst 'flu' ive gotten was wheni was 12; i puked once in a bucket and laid in bed for two days....
My mom got the vasccination once and she got a VERY ba dcase- IE almost drowned in lung fluids. A lot of people seem to get the vaccination and then get really sick two weeks later...
As to the chiropractor-
If it works but it isnt "Real" its still works.
If the insane man sees a dog tip over his glass of water, theres nothing to tell him it did or did not happen but impulses to his brain. Reality is highly over- simplified.
