Yeah,
I know, Palmistry can so addictive though. I started out just taking those online palmistry tests and then I worked my way up to learning about the different lines on the hands and different finger shapes and hand shapes. There's so much to remember though and I can't remember half of it without the aid of a book.
Here's a website put together by a guy who's been researching palmistry for years and he decided to post everything he's learned.
