about 4 years ago a friend of mine show me that thing i dont remeber the name of the program, it was for windows xp, and told me these 3 color lines are my emotional/fisical/intelectual stats based on my birthdate or something, now, 4 years later, i have downloaded an app called Biorhythm for my celphone and now it matches what it says with my life as it did 4 years ago... and now i remeber the day i did the french exam(idk NOTHING about french, i hate it) the biorhythm says something like 90% int, -80% emotional, and guess what, i passed the exam also i have a bipolar friend, she is like 100%x3 one day and the next -100% lol http://en.wikipedia.org/wiki/Biorhythm what you think about it?
It's BS. No offence. You can't predict the future based on dates and colours. There are alot of factors that go into the chemical balance of the brain that would make predicting your abilities next to %0. Diet, rest and excercise on any given day will change what your brain's capacity to preform is. Sure if you ate the same thing every day, stayed in the same room every day and excercised the exact same amount every day you might be able to predict the brain's performance and have an idea of what the future might have in store for said person. Although knowing exactly what they ate, where they stayed and how they excercised might be more telling.
If I were to speak of you in broad terms, you could and likely would, apply my words to whatever they fit.
An albino spider just ran over my fingers while I typed this! Srsly biorythms were quite popular in 1980, but without a proper hypothesis that backs up the claims, its nothing more than an excellent math example to teach students trigonometry.
Yeah let's put a sine here a cosine there, the life of a person and tada, you get the future ! Come on . There is a good episode of lie to me about that. Some people use some scientific concept, mix it with social relationship and put a cool name. There are also people telling you that you can be cured from the radio emission of some stones.
Well the wiki article you linked seems to have quite clear reasons why it is not plausible. I'd also say that there is power of suggestion at work for people who believe in that kind of stuff, self fulfilling prophecy.
