Cancer Zodiac Sign - Information On Cancer Astrology Sign

I don't know ANYTHING about astrology... but do you really base a person's personality based on the date they were born?

If I'm not mistaken, there are about... 6.6 billion people in the world. There are 12 signs. This means... 550 million people in the world have the same sign as this guy you're talking about (statistically speaking).

Again, I might catch a lot of crap for this, but... I suggest you TALK to the guy and get to know him... I read my horoscopes once, and it actually defined the exact opposite of who I am...

No Isneeze, you are right but I have noticed in life that many people do have the characteristic traits of their birth sign. But a lot more is involved too or we would all be the same as each other according to what our birth chart is. There is numerology chart, the nature vs nuture, how we precieve and process things, baggage we collect and hold onto and a lot of things that bring us to who we are.
