If you don't believe in acupuncture, it doesn't mean that it doesn't exist... [/b]
well it a good to be sceptic. as i say if he did it on the first day of flu and got cured it woulbe be more believable then waiting several days when the flu last several days. see it more probable he immune system did it. selective attenion people
The problem with this is:
1) Selection bias. Basically, you remember, and CHOOSE to remember, certain events more than others.
2) The problem of correlation/causation. Just because a happens simultaneously with b does NOT mean that a CAUSED b.
3) Placebo effect. Expecting for a to happen when b happens will probably cause a to happen when b happens--but this falls back to correlation/causation because b did not CAUSE a, the placebo effect caused a because of expectations you had.

see you choose to remeber that you had accumpunture and flu went a way so A cause B you forget that flu last several days so even if you didnt have accumpunture the cold would have went away soon anyway e.g. a day later.
