Very interesting. So how does someone know they have a gift for that sort of thing? Did you just try it out and find that you were good at it? Is it something anyone can do, or do you need special perceptive abilities?

but there are just some things I sort of...know from touching and looking at the hands in general rather than intimately analyzing the lines. That sounds a bit like nonsense, doesn't it?

No, it makes sense to me. :)
